Our biggest mistakes, were things we didn't do, companies we didn't buy.

I'm not entitled to have an opinion unless I can state the arguments against my position better than the people who are in opposition. I think that I am qualified to speak only when I've reached that state.

It's natural that you'd have more brains going into money management. There are so many huge incomes in money management and investment banking - it's like ants to sugar. There are huge incentives for a man to take up money management as opposed to, say, physics, and it's a lot easier.

There are two kinds of businesses: The first earns 12%, and you can take it out at the end of the year. The second earns 12%, but all the excess cash must be reinvested - there's never any cash. It reminds me of the guy who looks at all of his equipment and says, 'There's all of my profit.' We hate that kind of business.

To us, investing is the equivalent of going out and betting against the pari-mutuel system. We look for a horse with one chance in two of winning, and that pays three to one. In other words, we're looking for a mispriced gamble. That's what investing is, and you have to know enough to know whether the gamble is mispriced.

Move only when you have an advantage. It's very basic. You have to understand the odds and have the discipline to bet only when the odds are in your favor.

It's my guess that something like 5% of GDP goes to money management and itsattendant friction. I define it broadly - annuities, incentive pay, all trading, etc. Nobody else has used figures that high, but that's my guess. Worst of all, the people doing this are among the best and the brightest. Hundreds and thousands of engineers, etc. are going into hedge funds and investment banking. That is not an intelligent allocation of the brainpower of the civilization.
