Whatever it is that you do, if you have that passion and desire for it, that's the most important thing.

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.

If you interview five people about the same incident, and you see five different points of view, it makes you know what makes history so complicated. Something doesn't just occur. It's not like a scientific event. It's a human event. So the dimensions of it will be seen differently by different people.

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.

The one thing that John Kennedy did, above all else, was to energize young people to feel that they wanted to give something to their country.
