The best thing that happens to us is when a great company gets into temporary trouble...We want to buy them when they're on the operating table.

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

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.

Never be afraid to ask for too much when selling or offer too little when buying.

Never invest in a business you can't understand.

Basically, the single-most important decision in evaluating a business is pricing power.
