In my whole life, I have known no wise people (over a broad subject matter area) who didn't read all the time - none, zero. You'd be amazed at how much Warren reads - at how much I read. My children laugh at me. They think I'm a book with a couple of legs sticking out.

I think it is undeniably true that the human brain must work in models. The trick is to have your brain work better than the other person's brain because it understands the most fundamental models- ones that will do most work per unit.

It's not the bad ideas that do you in, but the good ones.

'Crowd folly', the tendency of humans, under some circumstances, to resemble lemmings, explains much foolish thinking of brilliant men and much foolish behavior - like investment management practices of many foundations represented here today. It is sad that today each institutional investor apparently fears most of all that its investment practices will be different from practices of the rest of the crowd.

It's my guess that something like 5% of GDP goes to money management and itsattendant friction. I define it broadly - annuities, incentive pay, all trading, etc. Nobody else has used figures that high, but that's my guess. Worst of all, the people doing this are among the best and the brightest. Hundreds and thousands of engineers, etc. are going into hedge funds and investment banking. That is not an intelligent allocation of the brainpower of the civilization.

Look at those hedge funds - you think they can wait? They don't know how to wait! I have sat for years at a time with $10 to $12 million in treasuries or municipals, just waiting, waiting...As Jesse Livermore said, 'The big money is not in the buying and selling...but in the waiting.'

The normal expectancy of the average investor - for example, the pension funds of AT&T or IBM - is 6% for a long time.
