I wish that after the war against Saddam Hussein we had been more effective at rebuilding Iraq quickly. I think had we done it from the provinces, in, rather than from Baghdad, out, we might have been more successful.

Search for role models you can look up to and people who take an interest in your career. But here's an important warning: you don't have to have mentors who look like you.

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.

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.
