I don't know anyone who said on their deathbed: 'Gee, I wish I'd spent more time at the office.'

Spend at least as much time researching a stock as you would choosing a refrigerator.

A lot of people got in at the wrong time. A lot of people did very well and some people said, "This is it. I'll never get back in again." And they maybe meant it, but they probably got back in again anyway.

The person that turns over the most rocks wins the game. And that's always been my philosophy.

Your investor's edge is not something you get from Wall Street experts. It's something you already have. You can outperform the experts if you use your edge by investing in companies or industries you already understand.

All you need for a lifetime of successful investing is a few big winners, and the pluses from those will overwhelm the minuses from the stocks that don't work out.

You should not buy a stock because it's cheap but because you know a lot about it.
