“And this is probably a good place for me to end by just saying that the issue of climate change is a perfect example of why young people have to lead. Because old people, they've created a mess, and then they'll be gone. And then you -- (applause) -- you're the ones who have to deal with it. And also what happens is old people get set in their ways. So the older you get, the more likely you are to say, that's how it's always been so that's how I'm going to keep on doing it -- even if there's a better way to do things. Young people, they're asking, well, why do I have to do it that way? Let's try it this way. And that kind of willingness to accept challenges and try things in a new way, to not be stuck in the past, or to look towards the future, that's what all of you represent.”

“And so we can preserve great traditions -- music, food, dance, language, art -- but if there’s a tradition anywhere in Africa, or here in the United States, or anywhere in the world that involves treating people differently because you’re scared of them, or because you're ignorant about them, or because you want to feel superior to them, it's a bad tradition. And you have to challenge it. And you can't accept excuses for it. […] But the truth of the matter is, is that if you’re treating people differently just because of who they love and who they are, then there’s a connection between that mindset and the mindset that led to racism, and the mindset that leads to ethnic conflict. It means that you’re not able to see somebody else as a human being. And so you can’t, on the one hand, complain when somebody else does that to you, and then you’re doing it to somebody else. You can’t do it. There’s got to be some consistency to how you think about these issues. And that’s going to be up to young people -- because old people get stuck in their ways. […] And that doesn’t mean that everything suddenly is perfect. It just means that, young people, you can lead the way and set a good example. But it requires some courage, because the old thinking, people will push back at you. And if you don’t have the convictions and the courage to be able to stand up for what you think is right, then cruelty will perpetuate itself.”

“And, finally, our nations are strongest when we empower our young people –- because ultimately, you're the one who has to break down these old stereotypes and these old barriers, these old ways of thinking. Prejudices and stereotypes and assumptions -- those are what happens to old minds like mine. I'm getting gray hair now. I was more youthful when I first started this office. And that’s why young people are so important in these efforts.”

“We’ll continue to help India deal with the impacts of climate change -- because you shouldn’t have to bear that burden alone. As we keep working for a strong global agreement on climate change, it's young people like you who have to speak up, so we can protect this planet for your generation. I'll be gone when the worst effects happen. It's your generation and your children that are going to be impacted.”

“We get Bergdahl who was a traitor, and they get five of the greatest killers that they've wanted for eight years. We get Bergdahl — I call it the five for one trade. For the Iran deal, where we get nothing, we get nothing. They get ultimately, they have the path, beautiful path, they'll get way, way earlier than that. They'll get nuclear weapons, so if you get Trump you're going to see a lot of changes to that deal. That'll happen fast.”

“As you get old you have to train smarter. Every young guy goes through it; every young guy says I'm invincible, it will never happen to me. The body is like a car or machine, you work it so often that eventually it's going to break down.”

“I'm just saying -- you can't prevent other people from disappointing you. It's bound to happen at some point. We're all only human. What you can do is decide how you're going to deal with it.”

“Since people are going to be living longer and getting older, they'll just have to learn how to be babies longer.”

“People don't change. If anything, you get more set in your ways as you get older, not less”

“You get tired of dealing with how other people think of what you're doing. It finally gets to the point where you realize that if you're going to do it the way you want, you have to do it yourself. That might mean putting up the money to do it yourself.”
