The game is to keep learning, and I don't think people are going to keep learning who don't like the learning process.

Practically everybody (1) overweighs the stuff that can be numbered, because it yields to the statistical techniques they’re taught in academia, and (2) doesn’t mix in the hard-to-measure stuff that may be more important. That is a mistake I’ve tried all my life to avoid, and I have no regrets for having done that.

It's not the bad ideas that do you in, but the good ones.

If you, like me, lived through 1973-74 or even the early 1990s... There was a waiting list to get OUT of the country club - that's when you know things are tough. If you live long enough, you'll see it.

If you always tell people why, they'll understand it better, they'll consider it more important, and they'll be more likely to comply.

I'm a bull on Berkshire Hathaway. There may be some considerable waiting, but I think there are some good days ahead.
