When I look at Franklin Roosevelt's leadership, I think the most important quality he had during the Depression and the war was this absolute confidence in himself, in his country, really in the American people. He was able to exude that confidence and almost project it.

One of the important qualities that I think is often overlooked is just energy. It's vitality, and sort of a life force that some people have and others don't. Probably that is connected to a love of whatever it is that they're doing. Another quality that I think is central is confidence. Again, some people are more blessed with that than others.

Better to have your enemies inside your tent pissing out, then to have them outside your tent pissing in.

I think the most important advice is, a person doesn't have to find out right away. It's not like their first attempt at finding a profession is the only one they're going to find. I might well have gone down other paths, and it still might have been okay. But if you find something that you love, and if it keeps deepening with each new experience, then just stay with it.

You can be enormously effective for a period of time, because it's almost like there's an engine in you that needs to keep going, and you have a greater drive than other people - who may be more happy and balanced in life - because you have to keep going out and proving yourself over and over again.

What the American Dream means to me is the fact that - what founded this country - when I think about those posters that were put up in Europe, which said, "Come to America and you'll have golden sidewalks. The land will be yours." There was something so inspirational about the fact that these immigrants from all over the world felt that here was a place of freedom, a place of opportunity.

Excitement about things became a habit, a part of my personality, and the expectation that I should enjoy new experiences often engendered the enjoyment itself.
