There is nothing better than being in a classroom with really, really brilliant students, and opening up new worlds to them. That's what I love doing.

I find that the great majority of public servants across the entire political spectrum come because they believe in the United States and they want to change the world.

You know, life is not one in which you just get to choose the things every day that come easily to you. And it's also true - and this is the self-esteem problem - you learn that there are people who are better at things than you are.

Today's headlines and history's judgment are rarely the same. If you are too attentive to the former, you will most certainly not do the hard work of securing the latter.

What the United States has done hasn't always been liked or popular. But if you look at some of the most populous places in the world - China, India - the United States is not only respected but, in fact, popular.

At no time did I intend to, or do I believe that I did put forward false information to the American people.

Today's headlines and history's judgement are not the same.
