No one built this country on their own. This nation is great because we built it together.

There are times where I'd say the Oval Office, you use to gather the facts. The decisions you probably make late at night, or at least I do. But there are some times where you think you've made a decision, but during that walk, where you're announcing the decision, you've just got to make sure that, you're prepared to live with it, because as you know George, a lot of these decisions are not - the outcomes are uncertain.

Part of what makes me most optimistic is if you look at the attitudes of young people. Across the board, young people are much more comfortable with respecting differences. They are much more comfortable with diversity.

I believe, in the words of Dr. Martin Luther King Jr., that there is such a thing as being too late, and when it comes to climate change, that hour is almost upon us.
