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.

When you are an historian, there's probably nothing that matters more than to be recognized by your colleagues in your own profession. I was lucky enough to win the Pulitzer Prize for History. I had to give a talk right after that to some young people. The most important thing to tell them, I think, is that you can't ever know that it's going to turn out that way.

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.

I think after Sandy Hook, when Obama went out, and he talked a lot about gun control and met with the parents, there was a sense that something was going to happen. But then, I guess, the power of special interests was greater than public sentiment.

I keep thinking that history runs in cycles, and that some day certain large issues will come before the country again. There will be leaders that inspire young people. I don't think it means that it's over forever, but I'm getting pretty impatient. I'm hoping it comes soon, so that my young people can know that experience that we knew in the '60s, and that the World War II generation knew during the '40s.

Go ahead, and fear not. You will have a full library at your service.

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