Some people seem to think there's no trouble just because it hasn't happened yet. If you jump out the window at the 42nd floor and you're still doing fine as you pass the 27th floor, that doesn't mean you don't have a serious problem. I would want to address the problem right now.

Whenever you think something or some person is ruining your life, it's you. A victimization mentality is so debilitating.

The Berkshire-style investors tend to be less diversified than other people. The academics have done a terrible disservice to intelligent investors by glorifying the idea of diversification. Because I just think the whole concept is literally almost insane. It emphasizes feeling good about not having your investment results depart very much from average investment results. But why would you get on the bandwagon like that if somebody didn't make you with a whip and a gun?

I think I've been in the top 5% of my age cohort all my life in understanding the power of incentives, and all my life I've underestimated it.

I think it would be a great improvement if there were no D&O insurance . The counter-argument is that no-one with any money would serve on a board. But I think net net you'd be better off.

I think there's something to be said for developing the disposition to own stocks without fretting.

We believe there should be a huge area between everything you should do and everything you can do without getting into legal trouble. I don't think you should come anywhere near that line. We don't deserve much credit for this. It helps us make more money. I'd like to believe that we'd behave well even if it didn't work. But more often, we've made extra money from doing the right thing. Ben Franklin said I'm not moral because of it's the right thing to do - but because it's the best policy.

I think the main figure that matters to all of us, including people in the media, is: How does GDP per capita grow? And those figures have been very good. There is a huge flux both up and down, so it isn't like we're all static in status. What's important is that pie grows.

I don't think vengeance is much good.
