In the end, the Impressionists made the right choice, which is one of the reasons that their paintings hang in every major art museum in the world. But this same dilemma comes up again and again in our own lives, and often we don’t choose so wisely. The inverted-U curve reminds us that there is a point at which money and resources stop making our lives better and start making them worse.

The lesson of the Impressionists is that there are times and places where it is better to be a Big Fish in a Little Pond than a Little Fish in a Big Pond, where the apparent disadvantage of being an outsider in a marginal world turns out not to be a disadvantage at all.

"Grazer and Cohn - two outsiders with learning disabilities-played a trick. They bluffed their way into professions that would have been closed to them. The man in the cab assumed that no one would be so audacious as to say he knew how to trade options if he didn't. And it never occurred to the people Brian Grazer called that when he said he was Brian Grazer from Warner Brothers, what he meant was that he was Brian Grazer who pushed the mail cart around at Warner Brothers. What they did is not "right," just as it is not "right" to send children against police dogs. But we need to remember that our definition of what right is, often as not, simply the way that people in positions of privilege close the door on those on the outside. David has nothing to lose, and because he has nothing to lose, he has the freedom to thumb his nose at the rules set by others. That's how people with brains a little bit different from the rest of ours get jobs as options traders and Hollywood producers-and a small band of protesters armed with nothing but their wits have a chance against the likes of Bull Connor"

Over the past decade, the anti-smoking movement has railed against the tobacco companies for making smoking cool and has spent untold millions of dollars of public money trying to convince teenagers that smoking isn't cool. But that's not the point. Smoking was never cool. Smokers are cool. Smoking epidemics begin in precisely the same way that the suicide epidemic in Micronesia began or word-of-mouth epidemics begin or the AIDS epidemic began, because of the extraordinary influence of Pam P. and Billy G. and Maggie and their equivalents-the smoking versions of R. and Tom Gau and Gaetan Dugas. In this epidemic, as in all others, a very small group-a select few-are responsible for driving the epidemic forward.

Goliath was blind to his approach — and then he was down, too big and slow and blurry-eyed to comprehend the way the tables had been turned. All these years, we’ve been telling these kinds of stories wrong. David and Goliath is about getting them right.

“Outlier” is a scientific term to describe things or phenomena that lie outside normal experience. In the summer, in Paris, we expect most days to be somewhere between warm and very hot. But imagine if you had a day in the middle of August where the temperature fell below freezing. That day would be outlier. And while we have a very good understanding of why summer days in Paris are warm or hot, we know a good deal less about why a summer day in Paris might be freezing cold. In this book I’m interested in people who are outliers—in men and women who, for one reason or another, are so accomplished and so extraordinary and so outside of ordinary experience that they are as puzzling to the rest of us as a cold day in August.

What do we tell our children? Haste makes waste. Look before you leap. Stop and think. Don't judge a book by its cover. We believe that we are always better off gathering as much information as possible and spending as much time as possible in deliberation.

…You can’t separate race from police shooting cases, but you also can’t say that’s the whole story. There’s something out of whack with the way we’ve structured relationships—not just between police officers and civilians, but between strangers of all kinds.
