For now, whether you are young or whether you're young at heart, I do have one final ask of you as your president, the same thing I asked when you took a chance on me eight years ago. I am asking you to believe not in my ability to bring about change, but in yours.

Moammar Gadhafi had more American blood on his hands than any individual other than Osama bin Laden.

You can’t let your failures define you. You have to let your failures teach you.

When I talked to [Donald Trump] about - our intelligence agencies, what I've said to him is - is that there are gonna be times where you've got raw intelligence that comes in and in my experience, over eight years, the intelligence community is pretty good about saying, "Look, we can't say for certain what this means." But there are gonna be times where the only way you can make a good decision is if you have confidence that the process is working, and the people that you put in charge are giving you their very best assessments.

I just want to go through Central Park and watch folks passing by. Spend the whole day watching people. I miss that.

In the Muslim world, this notion that somehow everything is the fault of the Israelis lacks balance - because there's two sides to every question. That doesn't mean that sometimes one side has done something wrong and should not be condemned. But it does mean there's always two sides to an issue. I say the same thing to my Jewish friends, which is you have to see the perspective of the Palestinians. Learning to stand in somebody else's shoes to see through their eyes, that's how peace begins. And it's up to you to make that happen.

When you see a Donald Trump and a Bernie Sanders, very unconventional candidates, have considerable success, then obviously there's something there that's being tapped into; a suspicion on globalization, a desire to reign in it's excesses, a suspicion of elites and governing institutions that people feel may not be responsive to their immediate needs. And that sometimes gets wrapped up in issues of ethnic identify or religious identity or cultural identity, and that can be a volatile mix.
