You're neither right nor wrong because other people agree with you. You're right because your facts are right and your reasoning is right - that's the only thing that makes you right. And if your facts and reasoning are right, you don't have to worry about anybody else.

Part of making good decisions in business is recognizing the poor decisions you've made and why they were poor. I've made lots of mistakes. I'm going to make more. It's the name of the game. You don't want to expect perfection in yourself. You want to strive to do your best. It's too demanding to expect perfection in yourself.

Never give up searching for the job that you’re passionate about. Try to find the job you’d have if you were independently rich. Forget about the pay. When you’re associating with the people that you love, doing what you love, it doesn’t get any better than that.

The stockmarket is a semi-psychotic creature given to extremes of elation and despair.

You are neither right nor wrong because the crowd disagrees with you.

Investing is the greatest business in the world because you never have to swing. You stand at the plate; the pitcher throws you General Motors at 47! U.S. Steel at 39! And nobody calls a strike on you. There's no penalty except opportunity. All day you wait for the pitch you like; then, when the fielders are asleep, you step up and hit it.

We try to exert a Ted Williams kind of discipline. In his book The Science of Hitting, Ted explains that he carved the strike zone into 77 cells, each the size of a baseball. Swinging only at balls in his "best" cell, he knew, would allow him to bat .400; reaching for balls in his "worst" spot, the low outside corner of the strike zone, would reduce him to .230. In other words, waiting for the fat pitch would mean a trip to the Hall of Fame; swinging indiscriminately would mean a ticket to the minors.
