Successful Investing takes time, discipline and patience. No matter how great the talent or effort, some things just take time: You can't produce a baby in one month by getting nine women pregnant.

I mean, we'll be pounding on the guy's chest, you know, on the floor, and you know, he's not going to just jump up all of a sudden. So it makes it tough. I mean, it's tough to be in the legislature, you know, and vote for something and then people say, well, you voted all this money and you know, it's all getting spent. It isn't getting spent. It's getting invested. But it's all getting spent. Nothing's happening.

Exercise humility and restraint.

If you buy the things you don't need, you will soon be selling the things that you need.

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.

I bought a company in the mid-90s called Dexter Shoe and paid $400 million for it. And it went to zero. And I gave about $400 million worth of Berkshire stock, which is probably now worth $400 billion. But I've made lots of dumb decisions. That's part of the game.

It is impossible to unsign a contract, so do all your thinking before you sign.
