As you look back at your life, there are just a million different things that have happened, just in the right way, to allow you to make your dreams come true. And you know, someone has all that under control.

It looks like the future's really bright.

When you launch in a rocket, you're not really flying that rocket. You're just sort of hanging on.

If you want something that's going to provide you with a lot of challenges and a variety of different things to do, then you really can't beat a place like the Air Force. I don't mean this to sound like a recruiting pitch. But it's been a lot of fun.

Science was something that really caught my attention. It was something I really could sink my teeth into.

I was always fascinated by science-fiction shows, shows like 'Star Trek' and 'Lost in Space.'

Like most kids growing up, I had a very wide interest. I was interested in everything. I tried to take advantage of everything, from the sciences to music to writing to literature.
