The greatest discovery of my generation is that a human being can alter his life by altering his attitudes.

I’m always disappointed when people don’t live up to their potential. I know that a number of people look down on themselves and consequently on everybody who looks like them. But that, too, can change.

We all need people who will give us feedback. That’s how we improve.

Always dream and shoot higher than you know you can do. Don’t bother just to be better than your contemporaries or predecessors. Try to be better than yourself.

To make headway, improve your head.

I care most about how people live their lives, what choices they make, and how they get the best from themselves.

I think that’s the single best piece of advice: constantly think about how you could be doing things better and questioning yourself.

Whoever I am, or whatever I am doing, some kind of excellence is within my reach.

If I am walking with two other men, each of them will serve as my teacher. I will pick out the good points of the one and imitate them, and the bad points of the other and correct them in myself.

I would say that one of the things I wish I could do differently would be to be more outgoing.
