I'm always interested in understanding the math of things and understanding as much as I can about all aspects of business. And what I learn today may be useful to me two years from now. That's really the wonderful thing about investments is your knowledge is cumulative.

Gold has two significant shortcomings, being neither of much use nor procreative.

Our investments continue to be few in number and simple in concept: The truly big investment idea can usually be explained in a short paragraph.

Long ago, Sir Isaac Newton gave us three laws of motion, which were the work of genius. But Sir Isaac's talents didn't extend to investing: He lost a bundle in the South Sea Bubble, explaining later, 'I can calculate the movement of the stars, but not the madness of men.' If he had not been traumatized by this loss, Sir Isaac might well have gone on to discover the Fourth Law of Motion: For investors as a whole, returns decrease as motion increases.

I don't want to give a lecture to this body that's out there. You know, I mean, having had the heart attack, I want to get it back functioning.

They lost very cushy lives, many of them.
