I'm proud to be associated with the value system at Berkshire Hathaway; I think you'll make more money in the end with good ethics than bad.

The first rule is that you can't really know anything if you just remember isolated facts and try and bang 'em back. If the facts don't hang together on a latticework of theory, you don't have them in a usable form.

I think time and time again, in reality, psychological notions and economic notions interplay, and the man who doesn't understand both is a damned fool.

If any successes has come to me, it came because I insisted on thinking things through. That's all I was capable of doing in life, was thinking pretty hard about trying to get the right answer, and then acting on it. I never learned to do anything else.

It's a real pleasure to earn the trust of your customers slowly over time by doing what's right.
