You can't start out at 20 in whatever your profession is and say, "I want to win an Olympic medal," or "I want to become president," or "I want to win the Pulitzer Prize." If you love what you're doing, it's sort of a nice thing that happens toward the end of your career, or in the middle of your career. It is not the reason you were doing it. The reason you were doing it is because every day you wake up in the morning and you can't wait to learn something new.

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.

The past is not simply the past, but a prism through which the subject filters his own changing self-image.

As much research as you think you're doing, you're going to mess up, without a question.

I liked the thought that the book I was now holding had been held by dozens of others.

The one thing that John Kennedy did, above all else, was to energize young people to feel that they wanted to give something to their country. I just hope, for young people of this generation, that they'll experience that feeling once again, that by working on large goals, they can do something more than their own individual ambition.

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.
