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.

Fortunately, I started very young, so I read music very well. And my favorite composers to play are Brahms and Mozart.

America is a country that went through an extremely difficult set of circumstances out of 9/11. And we've survived it as a country, and I think we've survived it as one people. And we all ought to be concentrating on trying to make sure that we move forward as one people out of that terrible experience.

[I'm] very fortunate and blessed person who still has a lot of living to do.

You will make a difference in the world, but not immediately. Your first obligation is to find something you like doing, because if you like doing it, you'll do it well.

I'm a strong believer that you have to have an equal opportunity to fail and to try things that are hard. I always tell my students, "Don't just take things that are easy for you. If you're really good at math, don't take just math. Take classes that make you write. If you're a really great writer, but bad at math, take math and make yourself work your way through it."
