Economics is in many respects the queen of the soft sciences. It's expected to be better than the rest. It's my view that economics is better at the multi-disciplinary stuff than the rest of the soft science. And it's also my view that it's still lousy.

If you took our top fifteen decisions out, we'd have a pretty average record. It wasn't hyperactivity, but a hell of a lot of patience. You stuck to your principles and when opportunities came along, you pounced on them with vigor.

Quoting Demosthenes, 'For what each man wishes, that he also believes to be true.' I would rather make money playing a piano in a whorehouse than arguing that no cost is incurred when employees are paid in stock options instead of cash. I am not kidding.

Hard work, honesty, if you keep at it, will get you almost anything.

If you get into the mental habit of relating what you're reading to the basic structure of the underlying ideas being demonstrated, you gradually accumulate some wisdom.

You must know the big ideas in the big disciplines, and use them routinely - all of them, not just a few. Most people are trained in one model - economics, for example - and try to solve all problems in one way. You know the old saying: to the man with a hammer, the world looks like a nail. This is a dumb way of handling problems.

Even if you assume that the whole economy would work better had we never had double taxation, having the envy and resentment of the richest paying low or no taxes screams of injustice. You have to have a fair system.
