The financial calculus that Charlie and I employ would never permit our trading a good night's sleep for a shot at a few extra percentage points of return. I've never believed in risking what my friends and family have and need in order to pursue what they don't have and don't need.

Risk comes from not knowing what you're doing.

I mean, Hank Paulson is in there [ Treasury] at the wrong time, probably shouldn't have taken the job. He's a friend of mine. But he knows markets, he knows corporations' work, he knows money, and he's got the interests of the country at heart.

Trust is like the air we breathe--when it's present, nobody really notices; when it's absent, everybody notices.

I've never been very fully employed either.

The critical investment factor is determining the intrinsic value of a business and paying a fair or bargain price.

I would say the most satisfying thing actually is watching my three children each pick up on their own interests and work many more hours per week than most people that have jobs at trying to intelligently give away that money in fields that they particularly care about.
