I think with Lyndon Johnson, the most important thing I learned was that he never had the sense of security that comes from inside. It always depended on other people making him feel good about himself, which meant that he was always beholden, continually needing to succeed. He could never stop. There was such a restlessness in him.

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

I still think about that one Jamiroquai video a lot.

Excitement about things became a habit, a part of my personality, and the expectation that I should enjoy new experiences often engendered the enjoyment itself.

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.

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.

I am a historian. With the exception of being a wife and mother, it is who I am. And there is nothing I take more seriously.
