Never invest in a business you can't understand

I think that actually people in my situation should be paying more tax.

The real fortunes in this country have been made by people who have been right about the business they invested in, and not right about the timing of the stock market.

People do, as long as you have markets, you'll have excesses.

Everybody's got a different circle of competence. The important thing is not how big the circle is. The important thing is staying inside the circle.

The fact that people will be full of greed, fear, or folly is predictable. The sequence is not predictable.

Failure comes from ego, greed, envy, fear, imitation. I have success not because I am smart, but because I am rational.
