I'd like to think that what my style of writing is, is an attempt not so much to judge the characters that I'm writing about, to expose them, to label them, to stereotype them, but instead to make them come alive for the reader with all their strengths and their flaws intact.

They all start competing against Lincoln as the greatest president. And the [library] building becomes the symbol, the memorial to that dream.

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.

Lyndon Johnson is still the most formidable, fascinating, frustrating, irritating individual I think I've ever known in my entire life. He was huge, a huge character, not only standing six feet four, but when you talked to him, he violated the normal human space between people. He was a great storyteller. The problem was that half his stories, I discovered, weren't true.

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

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.

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.
