“Studying in countries like China isn't only about your prospects in the global marketplace. It's not just about whether you can compete with your peers in other countries to make America stronger. It's also about whether you can come together and work together with them to make our world stronger. It's about the friendships you make, the bonds of trust you establish and the image of America that you project to the rest of the world.”

“Making your mark on the world is hard. If it were easy, everybody would do it. But it's not. It takes patience, it takes commitment, and it comes with plenty of failure along the way. The real test is not whether you avoid this failure, because you won't. it's whether you let it harden or shame you into inaction, or whether you learn from it; whether you choose to persevere.”

“Do not bring people in your life who weigh you down. And trust your instincts ... good relationships feel good. They feel right. They don't hurt. They're not painful. That's not just with somebody you want to marry, but it's with the friends that you choose. It's with the people you surround yourselves with.”

“You may not always have a comfortable life and you will notalways be able to solve all of the world's problems at oncebut don't ever underestimate the importance you can havebecause history has shown us that courage can be contagiousand hope can take on a life of its own.”

“But you see, a rich country like America can perhaps afford to be stupid.”

“No, you can't deny women their basic rights and pretend it's about your 'religious freedom'. If you don't like birth control, don't use it. Religious freedom doesn't mean you can force others to live by your own beliefs.”

“For we have a choice in this country. We can accept a politics that breeds division, and conflict, and cynicism. We can tackle race only as spectacle-as we did in the OJ trial-or in the wake of tragedy, as we did in the aftermath of Katrina-or as a fodder for the nightly news. We can play Reverend Wright's sermons on every channel, every day and talk about them from now until the election, and make the only question in this campaign whether or not the American people think that I somehow believe or sympathize with his most offensive words. We can pounce on some gaffe by a Hillary supporter as evidence that she's playing the race card, or we can speculate on whether white men will all flock to John McCain the general election regardless of his policies. We can do that. But if we do, I can tell you that in the next election, we'll be talking about some other distraction. And then another one. And then another one. And nothing will change. That is one option. Or, at this moment, in this election, we can come together and say, "Not this time.”
