Well, there are many things, whenever you look back, that you would've done differently. We're all human. We do our best at the time. I really wish that we had passed a comprehensive immigration bill because that would've really helped our country. We came close, but we couldn't.

I remember classes in college where the professor was espousing certain theories about how blacks were inherently less intelligent. But I learned a long time ago to give people the benefit of the doubt, not to assume that somebody was reacting to you because of race.

I am proud of the decision of this Administration to overthrow Saddam Hussein. I am proud of the liberation of 25 million Iraqis. And I'm proud to see an Iraq that is now emerging with a stronger government, a truly multiethnic, multi-sectarian government that's about to have its second set of elections, that's inviting private investment into Iraq, and that is making peace with its Arab neighbors.

Multilateral diplomacy is hard. It's slower, it's tougher, it's a bigger slog. I've learned that sometimes the things you'd most like to do something about, you really have difficulty unless the international community really mobilizes.

The American Founding Fathers gave us courts, independent jurists. They left room for civil society, which meant that citizens could directly associate in order to bring pressure on their governments. And they gave us a free press. They understood that you might have in the presidency someone who wanted to arrogate power into themselves. And they believed that was dangerous, having just experienced King George. And so they built a balanced system.

When somebody underestimated me, it made me want to prove them wrong.

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