I never allow myself to have an opinion on anything that I don't know the other side's argument better than they do.

There are a lot of things in life way more important than money. All that said, some people do get confused. I play golf with a man who says, " What good is health? You can't buy money with it."

Harvard and Yale concentrated with venture capitalists that got the best calls and brainpower. Very few firms made most of the money, and they made it in just a few periods. Everyone else returned between mediocre and lousy. When returns happened, envy rippled through institutional money management. The amount invested in venture capital went up 10 times post-1999. That later money was lost very quickly. It will happen again. I don't know anyone who successfully resists this stuff. It becomes a new orthodoxy.

Clever derivatives broke dozens of companies. It killed them. Bankrupt. We don't need these kinds of innovation in finance. It's OK to be boring in finance. What we want is innovation in widgets.

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.

The perfectly fabulous economics of this business could become grievously impaired.

If you skillfully follow the multidisciplinary path, you will never wish to come back. It would be like cutting off your hands.

If you're going to be an investor, you're going to make some investments where you don't have all the experience you need. But if you keep trying to get a little better over time, you'll start to make investments that are virtually certain to have a good outcome. The keys are discipline, hard work, and practice. It's like playing golf - you have to work on it.
