I'm a purist: I start to wrinkle my nose when the Cold War ends.

I don't think people are averse to thinking about things in a deep way, but we have limited time and opportunity to think about things in a deep way. I think that's why there is an appetite for non-fiction - it gives people the opportunity to reexamine ordinary experience and be smarter about it.

Where they come from matters. They're products of particular places and environments.

I interviewed one of the most powerful lawyers in the world and he told me, "At the time, it was the worst thing in the world not to be able to get a job at a fancy law firm, but it's the greatest thing that ever happened in my life." It was a humble acknowledgment of how forces much larger than himself shaped his career. I really wanted to bring that point home.

The trick to finding ideas is to convince yourself that everyone and everything has a story.

My writing model is my mother, who is a writer as well. She always valued clarity and simplicity above all else. If someone doesn't understand what you're writing, then everything else you do is superfluous. Irrelevant. If any thoughtful, curious reader finds what I do impenetrable, I've failed.

If you play an audiotape of a yawn to blind people, they'll yawn too.
