Once a month I play with a chamber music quartet. I play almost no solo music anymore because I so enjoy the interaction. The members of my quartet have become some of my best friends and so I really enjoy it now in ways that I didn't before.

You have to have a strong sense of your values and a strong sense of who you are, because there are a lot of events and a lot of people who will pull you in this direction or that direction.

I do have a favorite Zeppelin song, Larry, Black Dog.

We can't live true to our set of values unless American educational system is strong. I really believe that if we don't get that right we will not compete because we won't believe that our people can compete, and we'll turn inward. We won't lead. That will be bad for the world.

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.

I didn't run for student council president. I don't see myself in any way in elected office. I love policy. I'm not particularly fond of politics.

As Americans we like to believe that we're loved in international politics or that people like what we're doing. But we also recognize that we have an extraordinary responsibility to do what we think is right, and that sometimes what we do is not very popular.
