We had to get out of Chicago so quick. Election night happens, suddenly I'm talking to Ben Bernanke and Hank Paulson and trying to figure out whether the world's going to fly apart, and Michelle is trying to figure out where the girls are going to go to school. And we pack up and leave and basically our house in Chicago just became like a time capsule. My desk in my home office still had stacks of articles and bills and stuff from 2008.

By 2025 we expect new spacecraft designed for long journeys to allow us to begin the first ever crewed missions beyond the Moon into deep space. So we'll start by sending astronauts to an asteroid for the first time in history. By the mid-2030s I believe we can send humans to orbit Mars and return them safely to Earth. And a landing on Mars will follow and I expect to be around in see it.

I would say of all the things that have happened during the course of my presidency the knowledge that you have hundreds of thousands of people who have been killed, millions who have been displaced, [makes me] ask myself what might I have done differently along the course of the last five, six years.

The worst thing that colonialism did was to cloud our view of our past.

Around the world, Gandhi, Nelson Mandela -- what they did was hard. It takes time. It takes more than a single term. It takes more than a single president. It takes more than a single individual.

In the unlikely story that is America, there has never been anything false about hope.

I hoped for something else. It's a simple dream, but it speaks to us so powerfully because it is our dream - one that exists at the very center of the American experience. One that says if you're willing to work hard and take responsibility, then you'll have the chance to reach for something else; for something better.
