I often wonder why I changed Jobs !

I often wonder why I changed jobs. As I get updates on LinkedIn, I wonder why this is such a churning job market at a global level. and this seems to be at all levels right upto the CEO. Most of the companies seem to pay well and provide good working environments(some don't make the list, that's for a later post). Something didn't fit well into the logic of taking care of employees thereby reducing churn.

My own experience of changing jobs reveals that there's no pattern I could have followed with data I had years back. There have been quite different conditions with each move. As a Gen-Xer, I resolutely tried to stick on based on loyalty factors and my B-school learnings. It seemed that I had outgrown the system and needed to move on.

I must confess it just dawned on me with no prior warning that Culture fit was the key reason. I just didn't fit with "them" and "they" didn't synch with me. While all other business aspects remained the same, it just didn't feel like "it". To be frank, I get disappointed with all management and HR articles which blame the employee for not upgrading or having an attitude etc while not delving deeper into the Culture issue, resulting in finger pointing in all directions.

Culture as I see it is more of how best the fit is between two pieces of a puzzle so they can fit tight to provide a bigger picture. It need not be symbolic of similar aspirations e.g. A Sales person may still not fit into a Sales only culture. There are many aspects to this, not the least of which is the life stage of an employee or size of an organization. e.g. If you have no kids, you tend to get irritated when colleagues arrive late for meetings. When you do have kids, its too late to feel sorry to have been irritated years back. There are of course a Zillion factors and its wise to know your priority vs the company's. e.g. if you can't travel but you are in a Consulting position, its just too obvious whose priority will win in the end.

So feel free to assess the Culture of a company before accepting an offer. Ask them liberal questions, open ended to get a feel. Ask your friends and family if you would fit in that company. Explore multiple ways to get around the Culture question. If your Exec Recruiter is in a hurry (which seems more fast food nowadays), gently nudge them to get you a Culture input. After all its your career. You are here to help your Career , not any one else's.

Finally if you still get into a company and find you don't fit into the Culture, figure out a way to Transition soon. You will save a lot of Headache for everyone by being decisive. Believe me you will find an organization where you will flourish. and Maybe you will feel like the title of this post.

Download your Free Book: Networks, Crowds, and Markets: Reasoning About a Highly Connected World

Over the past decade there has been a growing public fascination with the complex "connectedness" of modern society. This connectedness is found in many incarnations: in the rapid growth of the Internet and the Web, in the ease with which global communication now takes place, and in the ability of news and information as well as epidemics and financial crises to spread around the world with surprising speed and intensity. These are phenomena that involve networks, incentives, and the aggregate behavior of groups of people; they are based on the links that connect us and the ways in which each of our decisions can have subtle consequences for the outcomes of everyone else.

Networks, Crowds, and Markets combines different scientific perspectives in its approach to understanding networks and behavior. Drawing on ideas from economics, sociology, computing and information science, and applied mathematics, it describes the emerging field of study that is growing at the interface of all these areas, addressing fundamental questions about how the social, economic, and technological worlds are connected.

The Art of Reading, Remembering, and Retaining More Books

 

Read fully at http://open.bufferapp.com/how-to-read-more-and-remember-it-all/?utm_content=buffer4bb2d&utm_medium=social&utm_source=linkedin.com&utm_campaign=buffer

 

“I just sit in my office and read all day.”

This is how Warren Buffett, one of the most successful people in the business world, describes his day. Sitting. Reading.

He advises everyone to read more, and that’s certainly a goal we can all get behind. Our personal improvements at Buffer regularly come back to the books we read—how we aim to read more and make reading a habit. I imagine you’re in the same boat as well. Reading more is one of our most common ambitions.

So how do we do it? And what are we to do with all that information once we have it?

Reading more and remembering it all is a discussion with a lot of different layers and a lot of interesting possibilities. I’m happy to lay out a few possibilities here on how to read more and remember it all, and I’d love to hear your thoughts below.

But first, let’s set some baselines …

How fast do you read?

One of the obvious shortcuts to reading more is to read faster. That’s likely the first place a lot of us would look for a quick win in our reading routine.

So how fast do you read?

Staples (yes, the office supply chain) collected speed reading data as part of an advertising campaign for selling e-readers. The campaign also included a speed reading tool that is still available to try. Go ahead and take the test to see how fast you read.

(My score was 337 words per minute. Yours?)

The Staples speed reading test includes data on how other demographics stack up in words per minute. According to Staples, the average adult reads 300 words per minute.

  • Third-grade students = 150 words per minute
  • Eight grade students = 250
  • Average college student = 450
  • Average “high level exec” = 575
  • Average college professor = 675
  • Speed readers = 1,500
  • World speed reading champion = 4,700

Average Reading Speed

Is reading faster always the right solution to the goal of reading more? Not always. Comprehension still matters, and some reports say that speed reading or skimming leads to forgotten details and poor retention. Still, if you can bump up your words per minute marginally while still maintaining your reading comprehension, it can certainly pay dividends in your quest to read more.

There’s another way to look at the question of “reading more,” too.

How much do you read?

There’s reading fast, and then there’s reading lots. A combination of the two is going to be the best way to supercharge your reading routine, but each is valuable on its own. In fact, for many people, it’s not about the time trial of going beginning-to-end with a book or a story but rather more about the story itself. Speed reading doesn’t really help when you’re reading for pleasure.

In this sense, a desire to read more might simply mean having more time to read, and reading more content—books, magazines, articles, blog posts—in whole.

Let’s start off with a reading baseline. How many books do you read a year?

A 2012 study by the Pew Research Center found that adults read an average of 17 books each year.

The key word here is “average.” There are huge extremes at either end, both those who read way more than 17 books per year and those who read way less—like zero. The same Pew Research study found 19 percent of Americans don’t read any books. A Huffington Post/YouGov poll from 2013 showed that number might be even higher: 28 percent of Americans haven’t read a book in the past year.

Wanting to read more puts you in pretty elite company.

5 ways to read more books, blogs, and articles

1. Read for speed: Tim Ferriss’ guide to reading 300% faster

Tim Ferriss, author of the 4-Hour Workweek and a handful of other bestsellers, is one of the leading voices in lifehacks, experiments, and getting things done. So it’s no wonder that he has a speed-reading method to boost your reading speed threefold.

His plan contains two techniques:

  1. Using a pen as a tracker and pacer, like how some people move their finger back and forth across a line as they read
  2. Begin reading each new line at least three words in from the first word of the line and end at least three words in from the last word

The first technique, the tracker/pacer, is mostly a tool to use for mastering the second technique. Ferriss calls this second technique Perceptual Expansion. With practice, you train your peripheral vision to be more effective by picking up the words that you don’t track directly with your eye. According to Ferriss:

Untrained readers use up to ½ of their peripheral field on margins by moving from 1st word to last, spending 25-50% of their time “reading” margins with no content.

The below image from eyetracking.me shows how this concept of perceptual expansion might look in terms of reading:

Perceptual Expansion

You’ll find similar ideas in a lot of speed reading tips and classes (some going so far as to suggest you read line by line in a snake fashion). Rapid eye movements called saccades occur constantly as we read and as our eyes jump from margins to words. Minimizing these is a key way to boost your reading times.

The takeaway here: If you can advance your peripheral vision, you may be able to read faster—maybe not 300 percent faster, but every little bit counts.

2. Try a brand new way of reading

Is there still room for innovation in reading? A couple of new reading tools say yes.

Spritz and Blinkist take unique approaches to helping you read more—one helps you read faster and the other helps you digest books quicker.

First, Spritz. As mentioned above in the speed reading section, there is a lot of wasted movement when reading side-to-side and top-to-bottom.

Spritz cuts all the movement out entirely.

Spritz shows one word of an article or book at a time inside a box. Each word is centered in the box according to the Optimal Recognition Point—Spritz’s term for the place in a word that the eye naturally seeks—and this center letter is colored red.

Spritz has yet to launch anything related to its technology, but there is a bookmarklet called OpenSpritz, created by gun.io, that lets you use the Spritz reading method on any text you find online.

Here is what OpenSpritz looks like at 600 words per minute:

OpenSpritz test

The Spritz website has a demo on the homepage that you can try for yourself and speed up or slow down the speeds as you need.

Along with Spritz is the new app Blinkist. Rather than a reimagining of the way we read, Blinkist is a reimagining of the way we consume books. Based on the belief that the wisdom of books should be more accessible to us all, Blinkist takes popular works of non-fiction and breaks the chapters down into bite-sized parts.

These so-called “blinks” contain key insights from the books, and they are meant to be read in two minutes or less. Yes, it’s a lot like Cliff Notes. Though the way the information is delivered—designed to look great and be eminently usable on mobile devices so you can learn wherever you are—makes it one-of-a-kind.

Here is an example of the Blinkist table of contents from Ben Horowitz’s The Hard Thing About Hard Things:

The Hard Thing About Hard Things

I’m sure we can agree that it’s a lot easier to read more when a book is distlled into 10 chapters, two minutes each.

3. Read more by making the time

Shane Parrish of the Farnam Street blog read 14 books in March, and he tackles huge totals like this month-in and month-out. How does he do it?

He makes it a priority, and he cuts out time from other activities.

What gets in the way of reading?

I don’t spend a lot of time watching TV. (The lone exception to this is during football season where I watch one game a week.)

I watch very few movies.

I don’t spend a lot of time commuting.

I don’t spend a lot of time shopping.

If you look at it in terms of raw numbers, the average person watches 35 hours of TV each week, the average commute time is one hour per day round-trip, and you can spend at least another hour per week for grocery shopping.

All in all, that’s a total of 43 hours per week, and at least some of that could be spent reading books.

4. Buy an e-reader

In the same Pew research study that showed Americans’ reading habits, Pew also noted that the average reader of e-books reads 24 books in a year, compared to a person without an e-reader who reads an average of 15.

Could you really read nine more books a year just by purchasing an e-reader?

Certainly the technology is intended to be easy-to-use, portable, and convenient. Those factors alone could make it easier to spend more time reading when you have a spare minute. Those spare minutes might not add up to nine books a year, but it’ll still be time well spent.

5. Read more by not reading at all

This is quite counterintuitive advice, and it comes from a rather counterintuitive book.

How to Talk About Books You Haven't Read

How to Talk About Books You Haven’t Read, written by University of Paris literature professor Pierre Bayard, suggests that we view the act of reading on a spectrum and that we consider more categories for books besides simply “have or haven’t read.” Specifically, Bayard suggests the following:

  • books we’ve read
  • books we’ve skimmed
  • books we’ve heard about
  • books we’ve forgotten
  • books we’ve never opened.

He even has his own classification system for keeping track of how he’s interacted with a book in the past.

UB book unknown to me

SB book I have skimmed

HB book I have heard about

FB book I have forgotten

++ extremely positive opinion

+ positive opinion

- negative opinion

extremely negative opinion

Perhaps the key to reading more books is simply to look at the act of reading from a different perspective? In Bayard’s system, he essentially is counting books he’s skimmed, heard about, or forgotten as books that he’s read. How might these new definitions alter your reading total for the year?

3 ways to remember what you read

Train your brain with impression, association, and repetition

A great place to start with book retention is with understanding some key ways our brain stores information. Here are three specific elements to consider:

  1. Impression
  2. Association
  3. Repetition

Let’s say you read Dale Carnegie’s How to Win Friends and Influence People, one of our favorites here at Buffer. You loved the information and want to remember as much as possible. Here’s how:

Impression – Be impressed with the text. Stop and picture a scene in your mind, even adding elements like greatness, shock, or a cameo from yourself to make the impression stronger. If Dale Carnegie is explaining his distaste for criticism, picture yourself receiving the Nobel Prize for Peace and then spiking the Nobel Prize onto the dais.

(Another trick with impression is to read an important passage out loud. For some of us, our sensitivity to information can be greater with sounds rather than visuals.)

Association – Link the text to something you already know. This technique is used to great effect with memorization and the construction of memory palaces. In the case of Carnegie’s book, if there is a particular principle you wish to retain, think back to a time when you were part of a specific example involving the principle. Prior knowledge is a great way to build association.

Repetition – The more you repeat, the more you remember. This can occur by literally re-reading a certain passage or in highlighting it or writing it down then returning to it again later.

Practicing these three elements of remembering will help you get better and better. The more you work at it, the more you’ll remember.

Focus on the four levels of reading

Mortimer Adler’s book, How to Read a Book, identifies four levels of reading:

  1. Elementary
  2. Inspectional
  3. Analytical
  4. Syntopical

Each step builds upon the previous step. Elementary reading is what you are taught in school. Inspectional reading can take two forms: 1) a quick, leisurely read or 2) skimming the book’s preface, table of contents, index, and inside jacket.

Where the real work (and the real retention begins) is with analytical reading and syntopical reading.

With analytical reading, you read a book thoroughly. More so than that even, you read a book according to four rules, which should help you with the context and understanding of the book.

  1. Classify the book according to subject matter.
  2. State what the whole book is about. Be as brief as possible.
  3. List the major parts in order and relation. Outline these parts as you have outlined the whole.
  4. Define the problem or problems the author is trying to solve.

The final level of reading is syntopical, which requires that you read books on the same subject and challenge yourself to compare and contrast as you go.

As you advance through these levels, you will find yourself incorporating the brain techniques of impression, association, and repetition along the way. Getting into detail with a book (as in the analytical and syntopical level) will help cement impressions of the book in your mind, develop associations to other books you’ve read and ideas you’ve learned, and enforce repetition in the thoughtful, studied nature of the different reading levels.

Keep the book close (or at least your notes on the book)

One of the most common threads in my research into remembering more of the books you read is this: Take good notes.

Bookmarks

Scribble in the margins as you go.

Bookmark your favorite passages.

Write a review when you’ve finished.

Use your Kindle Highlights extensively.

And when you’ve done these things, return to your notes periodically to review and refresh.

Shane Parrish of Farnam Street is a serial note taker, and he finds himself constantly returning to the books he reads.

After I finish a book, I let it age for a week or two and then pick it up again. I look at my notes and the sections I’ve marked as important. I write them down. Or let it age for another week or two.

Even Professor Pierre Bayard, the author of How to Talk About Books You Haven’t Read, identifies the importance of note-taking and review:

Once forgetfulness has set in, he can use these notes to rediscover his opinion of the author and his work at the time of his original reading. We can assume that another function of the notes is to assure him that he has indeed read the works in which they were inscribed, like blazes on a trail that are intended to show the way during future periods of amnesia.

I’ve tried this method for myself, and it has completely changed the way I perceive the books I read. I look at books as investments in a future of learning rather than a fleeting moment of insight, soon to be forgotten. I store all the reviews and notes from my books on my personal blog so I can search through them when I need to remember something I’ve read.

(Kindle has a rather helpful feature online, too, where it shows you a daily, random highlight from your archive of highlights. It’s a great way to relive what you’ve read in the past.)

Kindle highlights

It’s not important which method you have for note-taking and review so long as you have one. Let it be as simple as possible to complete so that you can make sure you follow through.

Over to you

How many books do you read each year? What will be your goal for this year? What’s your best tip for reading more and remembering more? I’d love to hear your thoughts in the comments.

Li Ka-Shing’s Money Wisdom

Hong Kong billionaire Li Ka-Shing shares some of his money wisdom, outlining an inspirational five-year plan to improve one’s lot in life

This article is translated from the original Chinese by Edmund Ng at CeoConnectz.

Complete Article is at http://mirror.e27.co/li-ka-shing-teaches-buy-car-house-5-years/ 

 

Suppose your monthly income is only RMB 2,000, you can live well. I can help you put money into five sets of funds. The first $600, second $400, third $300, fourth $200, fifth $500.

The first set of funds is used for living expenses. It’s a simple way of living and you can only be assigned to less than twenty dollars a day. A daily breakfast of vermicelli, an egg and a cup of milk. For lunch just have a simple set lunch, a snack and a fruit. For dinner go to your kitchen and cook your own meals that consist of two vegetables dishes and a glass of milk before bedtime. For one month the food cost is probably $500-$600. When you are young, the body will not have too many problems for a few years with this way of living.

Second set of funds: To make friends, expand your interpersonal circle. This will make you well off. Your phone bills can be budgeted at RMB 100. You can buy your friends 2 lunches a month, each at $150. Who should you buy lunch for? Always remember to buy lunch for people who are more knowledgeable than you, richer than you or people who have helped you in your career. Make sure you do that every month. After one year, your circle of friends should have generated tremendous value for you. Your reputation, influence, added value will be clearly recognized. You’ll also enhance your image of being good and generous.

Third set of funds: To learn. Monthly spend about RMB 50 to RMB 100 to buy books. Because you don’t have a lot of money, you should pay attention to learning. When you buy the books, read them carefully and learn the lessons and strategies that is being taught in the book. Each book, after reading them, put them into your own language to tell the stories. Sharing with others can improve your credibility and enhance the affinity. Also save up $200 per month to attend a training course. When you have higher income or additional savings, try to participate in more advanced training. When you participate in good training, not only do you learn good knowledge, you also get to meet like-minded friends who are not easy to come by.

Fourth set of funds: Use it for holidays overseas. Reward yourself by traveling at least once a year. Continue to grow from the experience of life. Stay in youth hostels to save cost. In a few years you would have travelled to many countries and have different experiences. Use that experience to recharge yourself so that you’ll continually have passion in your work.

Fifth set of funds: Invest. Save the $500 in your bank and grow it as your initial startup capital. The capital can then be used to do a small business. Small business is safe. Go to wholesalers and look for products to sell. Even if you lose money, you will not lose too much money. However, when you start earning money, it will boost your confidence and courage and have a whole new learning experience of running a small business. Earn more and you can then begin to buy long-term investment plans and get long-term security on your financial wealth being of yourself and your families. So that no matter what happens, there will be adequate funds and the quality of life will not decline.

Well, after struggling for a year and if your second year salary is still RMB 2,000, then that means you have not grown as a person. You should be really ashamed of yourself. Do yourself a favour and go to the supermarket and buy the hardest tofu. Take it and smash it on your head because you deserve that.

If your monthly income is at RMB 3,000, you must still work very hard. You must try to find a part time job. It will be great to find part time sales jobs. Doing sales is challenging, but it is the fastest way for you to acquire the art of selling and this is a very deep skill that you will be able to carry it for the rest of your career. All successful entrepreneurs are good sales people. They have the ability to sell their dream and visions. You’ll also meet many people that will be of value to you in the later part of your career. Once you’re in sales, you will also learn what sells and what not. Use the sensitivity of detecting market sentiments as a platform for running your business and in the identification of product winners in the future.

Try to buy minimal clothes and shoes. You can buy them all you want when you’re rich. Save your money and buy some gift for your loved ones and tell them your plans and your financial goals. Tell them why you are so thrifty. Tell them your efforts, direction and your dreams.

Businessmen everywhere need help. Offer yourself to do part time for any kind of opportunities. This will help to hone your will and improve your skills. You will start to develop eloquence and soon, you’ll be closer to your financial goals. By the second year, your income should be increased to at least RMB 5,000. Minimum it should be RMB 3,000, otherwise you would not be able to keep up with inflation.

No matter how much you earn, always remember to divide it into five parts proportionately. Always make yourself useful. Increase your investment in networking. When you increase your social investment, expand your network of contacts, your income also grows proportionately. Increase your investment in learning, strengthen your self confidence, increase investment in holidays, expand your horizons and increase investment in the future, and that will ultimately increase your income.

Maintain this balance and gradually you will begin to have a lot of surplus. This is a virtuous circle of life plans. Your body will start to get better and better as you get more nutrition and care. Friends will be aplenty and you will start to make more valuable connections at the same time. You will then have the conditions to participate in very high-end training and eventually you’ll be exposed to bigger projects, bigger opportunities. Soon, you will be able to gradually realize your various dreams, the need to buy your own house, car, and to prepare an adequate education fund for your child’s future.

Life can be designed. Career can be planned. Happiness can be prepared. You should start planning now. When you are poor, spend less time at home and more time outside. When you are rich, stay at home more and less outside. This is the art of living. When you are poor, spend money on others. When you’re rich, spend money on yourself. Many people are doing the opposite.

When you are poor, be good to others. Don’t be calculative. When you are rich, you must learn to let others be good to you. You have to learn to be good to yourself better. When you are poor, you have to throw yourself out in the open and let people make good use of you. When you are rich, you have to conserve yourself well and don’t let people easily make use of you. These are the intricate ways of life that many people don’t understand.

When you are poor, spend money so that people can see it. When you are rich, do not show off. Just silently spend the money on yourself. When you are poor, you must be generous. When you are rich, you must not be seen as a spendthrift. Your life would have come full circle and reach its basics. There will be tranquility at this stage.

There is nothing wrong with being young. You do not need to be afraid of being poor. You need to know how to invest in yourself and increase your wisdom and stature. You need to know what is important in life and what is worth investing in. You also need to know what you should avoid and not spend your money on. This is the essence of discipline. Try to avoid spending money on clothing, but buy a selective number of items that have class. Try to eat less outside. If you were to eat outside, do make sure you buy lunches or dinners and foot the bill. When buying people dinner, make sure you buy dinners for people who have bigger dreams than you, and work harder than you.

Once your livelihood is no longer an issue, use the remainder of your money to pursue your dreams. Spread your wings and dare to dream! Make sure you live an extraordinary life!

Famous theory from Harvard: The difference of a person’s fate is decided from what a person spends in his free time between 20:00 to 22:00 . Use these two hours to learn, think and participate in meaningful lectures or discussion. If you persist for several years, success will come knocking on your doors.

No matter how much you earn, remember to split your salary into five parts. Take care of your body so that it will still be in good shape. Invest in your social circle so that you will constantly meet new people where you can learn new knowledge from. Expanding your network will also have an important impact in how much you earn eventually. Travel every year and expand your horizons. Also keep abreast with the latest developments in the industry. If you follow this plan diligently, you will soon see big surplus in your funds.

Whatever happened in the past is over. Do not dwell on past mistakes. There’s no point crying over spilt milk. Everybody makes mistakes. It’s what you learn from the mistakes, and promising yourself not to repeat those mistakes that matters. When you miss opportunities, don’t dwell on it, as there are always new opportunities on the horizon.

Being able to smile when being slightly misunderstood is good upbringing. When you’re wronged and you smile with calmness, it is generosity. When you’re being taken advantage of and you can smile, you’re being open-minded. When you are helpless and you can do a philosophical smile, you’re in a calm state. When you’re in distress and you can laugh out loud, you’re being generous. When you’re looked down and you can calmly smile, you’re being confident. When you’re being jilted in relationships and you can smile it off, you’re being suave.

There are many people who are struggling to make ends meet. It doesn’t matter if you are rich or poor. There are lessons for all to learn from Li Ka Shing.

Download the Classic Book: The Elements of Statistical Learning

During the past decade has been an explosion in computation and information technology. With it has come vast amounts of data in a variety of fields such as medicine, biology, finance, and marketing. The challenge of understanding these data has led to the development of new tools in the field of statistics, and spawned new areas such as data mining, machine learning, and bioinformatics. Many of these tools have common underpinnings but are often expressed with different terminology. This book descibes the important ideas in these areas in a common conceptual framework. While the approach is statistical, the emphasis is on concepts rather than mathematics. Many examples are given, with a liberal use of color graphics. It should be a valuable resource for statisticians and anyone interested in data mining in science or industry. The book's coverage is broad, from supervised learning (prediction) to unsupervised learning. The many topics include neural networks, support vector machines, classification trees and boosting--the first comprehensive treatment of this topic in any book.

This major new edition features many topics not covered in the original, including graphical models, random forests, ensemble methods, least angle regression & path algorithms for the lasso, non-negative matrix factorization and spectral clustering. There is also a chapter on methods for ``wide'' data (italics p bigger than n), including multiple testing and false discovery rates.


Trevor Hastie, Robert Tibshirani, and Jerome Friedman are professors of statistics at Stanford University. They are prominent researchers in this area: Hastie and Tibshirani developed generalized additive models and wrote a popular book of that title. Hastie wrote much of the statistical modeling software in S-PLUS and invented principal curves and surfaces. Tibshirani proposed the Lasso and is co-author of the very successful {italics An Introduct ion to the Bootstrap}. Friedman is the co-inventor of many data-mining tools including CART, MARS, and projection pursuit.
