I don't believe in over-diversification. I prefer to focus on a few good ideas.

The great question which, in all ages, has disturbed mankind, and brought on them the greatest part of their mischiefs, has been, not whether there be power in the world, nor whence it came, but who should have it.

I don't try to predict the market. I just try to buy stocks that are cheap.

I'm not afraid of aging. I think it's a privilege to grow old.

Quality is not a technique, it is a philosophy.
