there are all kinds of wonderful new inventions that give you nothing as owners except the opportunity to spend a lot more money in a business that's still going to be lousy. The money still won't come to you. All of the advantages from great improvements are going to flow through to the customers.

The idea of caring is that someone is making money faster [than you are] is one of the deadly sins. Envy is a really stupid sin because it’s the only one you could never possibly have any fun at. There’s a lot of pain and no fun. Why would you want to get on that trolley?

You don't have to have perfect wisdom to get very rich - just a bit better than average over a long period of time.

It's been my experience in life if you just keep thinking and reading, you don't have to work.

It’s not greed that drives the world, but envy.

The liabilities are always 100 percent good. It's the assets you have to worry about.

It's natural that you'd have more brains going into money management. There are so many huge incomes in money management and investment banking - it's like ants to sugar. There are huge incentives for a man to take up money management as opposed to, say, physics, and it's a lot easier.
