I've never really been a workaholic.

We've organized human potential and have been better at using human potential better than any country on the face of the Earth. That's because we've recognized that our national creed, our national identity, is that it doesn't matter where you're from, it matters where you're going. You can come from hard circumstances and do great things. We've got to make that true for a whole variety of people who no longer feel that.

The most important lesson I think I could impart is don't let anyone determine what your horizons are going to be. You get to determine those yourself. The only limitations are whatever particular talents you happen to have and how hard you're willing to work. And if you let others define who you ought to be, or what you ought to be because they put you in a category, they see your race, they see your gender and they put you in a category. You shouldn't let that happen.

I laugh almost everyday. I have a good sense of humor, so I'm always finding something funny.

I stick to playing Brahms, but I love listening to Led Zeppelin, and I've also been a big fan of Earth Wind and Fire since the Seventies and of The Gap Band since the Eighties.

There was no silver bullet that could have prevented the 11 September attacks. There was nothing demonstrating or showing that something was coming in the United States. If there had been something, we would have acted on it.

Your friends and your family, if you're close to them, they won't let you get too far from who you were or from who you are. And so I love staying close to people who've always known me. That's probably the best leavening that you could possibly have.
