America cannot do most of what needs to be done alone. You need friends. And we have good friends around the world. We have friends with whom we share values in Europe and Asia - thanks to the forward march of democracy - in Latin America, in Africa, and increasingly in the Middle East.

I never found anybody I wanted to spend my life with. People say, "Didn't you want to get married?" Well, sure, but it's not abstract, there has to be someone you want to marry. I'm pretty traditional. Marriage would have to come first, before kids.

I hope that all of us who were fortunate enough to have benefited will put our time, our resources and our efforts into making sure that kids, particularly kids without means, have a way to achieve.

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.

Separation of powers is a problem for foreign policy.

I'm actually genuinely optimistic about the United States and what's possible in the United States. And when you're out here, you see Americans across racial and economic and socioeconomic lines working together. And you maybe get a little bit less cynical than when you sit in the seat of kind of the epicenter of it all.

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.
