Go to bed smarter than when you woke up.

In my life there are not that many questions I can't properly deal with using my $40 adding machine and dog-eared compound interest table.

It’s not greed that drives the world, but envy.

The game of life is the game of everlasting learning. At least it is if you want to win.

I talked to one accountant, a very nice fellow who I would have been glad to have his family marry into mine. He said, "What these other accounting firms have done is very unethical. The [tax avoidance scheme] works best if it's not found out [by the IRS], so we only give it to our best clients, not the rest, so it's unlikely to be discovered. So my firm is better than the others." [Laughter] I'm not kidding. And he was a perfectly nice man. People just follow the crowd...Their mind just drifts off in a ghastly way.

Over the long term, the eclipse rate of great civilizations being overtaken is 100%. So you know how it's going to end. (Laughter) I'm more optimistic about the staying power of what's good in this country. But just because you have a wonderful spouse doesn't mean you should treat her badly. You have the feeling that some of the old virtues [that made this country great] are lessening. But there's so much good and so much strength left that I would not expect this country to suddenly founder.

If you buy something because it's undervalued, then you have to think about selling it when it approaches your calculation of its intrinsic value. That's hard. But if you buy a few great companies, then you can sit on your ass. That's a good thing.
