If the strong exploit the weak, democracy will not be stable.

When I went off to college, I was expecting to be a concert musician. In music school I heard all of these kids who were just unbelievable. And I understand that you can be very, very good, but there's something that separates very, very good from great, and I knew that I wasn't great.

So I think, if September 11 taught us anything, it taught us that we're vulnerable, and vulnerable in ways that we didn't fully understand.

My favorite quote is Thomas Jefferson`s "The God who gave us life gave us liberty at the same time." Well, he was a slave-owner. But these institutions, while they weren't perfect at the time, did allow people to prosper and to continue to struggle and build toward them. That's what you need, is good institutions and I think people will eventually live up to them.

I think America is still a bright, shining city on the hill - not because we're perfect but because we struggle in our imperfections every day.

I play classical music almost exclusively. I never mastered jazz or gospel in the way that my mother did. She was a fine improvisational musician. I pretty much have to stick to what's written on the page.

It is possible to work across the aisle in Washington, but it's hard. And I think it's been made worse by the kind of 24-hour news cycle, the fact that everything is on TV before you can work things out quietly. I think it's the intensity of information that makes it feel more difficult to get things done. But I didn't leave with a bitter taste about the politics. The one thing that I would say is, I do think there is an unfortunate tendency to turn political differences, or policy differences, into critiques of one another's character or motives, and that's unfortunate.
