Our job is to find a few intelligent things to do, not to keep up with every damn thing in the world.

Tthe 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.... You may have noticed students who just try to remember and pound back what is remembered. Well, they fail in school and in life.

Recognize reality even when you don't like it-especially when you don't like it.

To say accounting for derivatives is Americais a sewer is an insult to sewage.

It is way less certain to be a wonderful business in the future. The threat is alternative mediums of information. Every newspaper is scrambling to parlay their existing advantage into dominance on the Internet. But it is way less sure [that this will occur] than the certainty 20 years ago that the basic business would grow steadily, so there's more downside risk. The perfectly fabulous economics of this business could become grievously impaired.

Wesco had a market capitalization of $40 million when we bought it [in the early 1970s]. It's $2 billion now. It's been a long slog to a perfectly respectable outcome - not as good as Berkshire Hathaway or Microsoft, but there's always someone in life who's done better.

It's in the nature of stock markets to go way down from time to time. There's no system to avoid bad markets. You can't do it unless you try to time the market, which is a seriously dumb thing to do. Conservative investing with steady savings without expecting miracles is the way to go.
