The best advice I can give anybody is to try to understand who you are and what you want to do, and don't be afraid to go down that road and do whatever it takes and work as hard as you have to work to achieve that.

I've spent my whole life not talking to people, and I don't see why I should start now.

All adventures, especially into new territory, are scary.

When you can feel that close to something you're used to seeing from this great distance, well, it changes a person.

Even though NASA tries to simulate launch, and we practice in simulators, it's not the same - it's not even close to the same.

I don't have any nicknames.

When you're getting ready to launch into space, you're sitting on a big explosion waiting to happen.
