It's not supposed to be easy. Anyone who finds it easy is stupid.

So you can get very remarkable investment results if you think more like a winning pari-mutuel player. Just think of it as a heavy odds against game full of craziness with an occasional mispriced something or other. And you're probably not going to be smart enough to find thousands in a lifetime. And when you get a few, you really load up. It's just that simple.

It's human nature to extrapolate the recent past into the future, but it's terrible that managements go along with this.

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.

This is an amazingly sound place. We are more disaster-resistant than most other places. We haven't pushed it as hard as other people would have pushed it. I don't want to go back to Go. I've been to Go. A lot of our shareholders have a majority of their net worth in Berkshire, and they don't want to go back to Go either.

Those of us who have been very fortunate have a duty to give back. Whether one gives a lot as one goes along as I do or a little and then a lot [when one dies] as Warrendoes is a matter of personal preference. I would hate to have people ask me for money all day long.

This is a good life lesson: getting the right people into your system is the most important thing you can do.
