Success in investing doesn't correlate with I.Q. Once you are above the level of 25; once you have ordinary intelligence, what you need is the temperament to control the urges that get other people into trouble in investing.

Buy companies with strong histories of profitability and with a dominant business franchise.

All there is to investing is picking good stocks at good times and staying with them as long as they remain good companies.

Don't invest in pieces of papers (stocks), invest in great businesses underlying them.

Good big decisions do not take time at all, if they do you are in trouble.

You're working because you want to change the world. You want to make it better. Why isn't the company that you work for, worthy not just of your time but your money as well? I mean, but we don't have a concept of that. That's not how we think about companies, and I think it's sad, because companies are most of our effort. They're where most of people's time is, where a lot of the money is, and so I think I'd like for us to help out more than we are.
