I've always said as a political scientist that "culture" is what we use when we can't explain things. I think it's more about accessibility. Part of the problem is that this is an expensive game [golf]. I know in a couple of places where there are black members, and they come from pretty much the same socioeconomic level that the white members come from.

In the segregated South, education was almost like armor. It was a way to put yourself in a category where even with the slings and arrows and humiliations of racism and segregation, somehow you had better control of the situation. I always said my parents understood that you might not be able to control your circumstances, but they and their parents believed that you could control your reaction to your circumstances.

Everywhere that I go in the world, people desperately look to American leadership in all of their world's most difficult problems. You can look at any region of the world and the United States is still the country to which those regions look for leadership.

Most days are not overwhelmingly successful in your life. And what really marks whether you're going to be successful is how well you deal with the bad days, not how well you deal with the good ones.

We need to move beyond the idea that girls can be leaders and create the expectation that they should be leaders.

It hasn't yet materialized that I went into sports management, but I haven't ruled it out yet, either. I only half-jokingly remarked that I'd love to be the commissioner of the NFL. But as I recently told current Commissioner Roger Goodell, that job looked a lot more appealing when I was struggling with the Russians and the Iranians everyday.

Our work has only begun. In our time we have an historic opportunity to shape a global balance of power that favors freedom and that will therefore deepen and extend the peace. And I use the word power broadly, because even more important than military and indeed economic power is the power of ideas, the power of compassion, and the power of hope.
