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.

I think the most important thing I wanted to say at various times to Franklin and Eleanor Roosevelt was that it seemed so sad to me that - I really believe they loved each other and had a great deal of affection - but because of that early hurt in their marriage, there was a certain kind of distance from then on, until their deaths actually. So at times, I just wanted to push them together and say, "Come on, you guys! I know you love each other. This is crazy!"

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

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

There are 20,000 million books I could have to read, but I can pick the ones and know that I'm learning something that I didn't know before. That's the glory of writing. It's not even so much the writing, it's what you learn - especially history - because so much of it is research.

What interested me most about the Kennedys was the family situation. Somehow, they had created this family that lasted over time, they had a sense of connection to one another. Especially now, when people are spread all over the country and they don't see grandparents and parents, this family bonded together.

My books are written with a strong chronological spine.
