When I do research, I have done - 90 percent of my time is the research, the other ten percent is the writing. So I don't have to face a blank piece of paper. I can look at this as a quote that I have from somewhere.

It took me five years on Lyndon Johnson, ten years on the Kennedys, six years on the Roosevelts. Inevitably, you get shaped by the people that you're thinking about during that period of time.

Sometimes people will find things that are wrong. Sometimes they will even find an approach that you took wrong. If you think you took the right approach, then you just absorb the criticism, but you don't change your mind.

When I look at what a writer owes to the reader, it's critical to know that everything you're writing about is not made up in your head. I feel that unless you can document and be certain about what it is that you're writing about, the reader is going to lose faith in your own integrity.

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.

What the American Dream means to me is the fact that - what founded this country - when I think about those posters that were put up in Europe, which said, "Come to America and you'll have golden sidewalks. The land will be yours." There was something so inspirational about the fact that these immigrants from all over the world felt that here was a place of freedom, a place of opportunity.

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.
