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.

If your ambition comes at the price of an unbalanced life, that there's nothing else that gives you comfort but success, it's not worth it.

People will love him (Theodore Roosevelt) for the enemies he has made.

What I think I've learned is that you're never going to get it all right, and you can't obsess about having a fact wrong or a date wrong or something like that, as long as you tried as best you could. If you've done the kind of research that you're sure is pretty good, then you just have to have confidence in it, so that nothing is perfect in life. I think that is what the criticism has helped me to understand.

My books are written with a strong chronological spine.

Washington was a typical American. Napoleon was a typical Frenchman, but Lincoln was a humanitarian as broad as the world. He was bigger than his country - bigger than all the Presidents together. We are still too near to his greatness,' (Leo) Tolstoy (in 1908) concluded, 'but after a few centuries more our posterity will find him considerably bigger than we do. His genius is still too strong and powerful for the common understanding, just as the sun is too hot when its light beams directly on us.' (748)

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.
