I think it is one of the most extraordinary elections, a turning point for our country and for the world. That remarkable young man [Barack Obama] has kept his demeanor, kept his temperament and has shown a power to inspire. I see what energy that he has inspired among the young. Well, it inspires us old goats too.

I had been writing for about twelve years. I knew pretty well how you could find things out, but I had never been trained in an academic way how to go about the research.

I could not do what I do without the kindness, consideration, resourcefulness and work of librarians, particularly in public libraries... What started me writing history happened because of some curiosity that I had about some photographs I'd seen in the Library of Congress.

The pull, the attraction of history, is in our human nature. What makes us tick? Why do we do what we do? How much is luck the deciding factor?

Develop and protect a moral sensibility and demonstrate the character to apply it. Dream big. Work hard. Think for yourself. Love everything you love, everyone you love, with all your might. And do so, please, with a sense of urgency, for every tick of the clock subtracts from fewer and fewer...

When you start to write, things begin to come into focus in a way they don't when you're not writing. It's a very good way to find out how much you don't know because you learn specifically what you need to know that you don't know at the moment by writing.

I love to go to the places where things happen. I like to walk the walk and see how the light falls and what winter feels like.
