I don't know anyone who is more admired and respected in the international community than President Karzai, for his strength, for his wisdom and for his courage to lead this country first in the defeat of the Taliban and now in rebuilding a democratic and unified Afghanistan. And I can tell you I am with foreign ministers and with heads of state all over the world. I sit in the councils of NATO. I sit with the EU. I sit with people all over the world and there is great admiration for your president and also for what the Afghan people are doing here.

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.

The most important lesson I think I could impart is don't let anyone determine what your horizons are going to be. You get to determine those yourself. The only limitations are whatever particular talents you happen to have and how hard you're willing to work. And if you let others define who you ought to be, or what you ought to be because they put you in a category, they see your race, they see your gender and they put you in a category. You shouldn't let that happen.

Every life is capable of greatness.

We [USA] need to deal with our problems here at home if we're going to be strong enough to lead abroad.

My Fox guys, I love every single one of them.

So I think, if September 11 taught us anything, it taught us that we're vulnerable, and vulnerable in ways that we didn't fully understand.
