The most important steps that I followed were studying math and science in school. I was always interested in physics and astronomy and chemistry and I continued to study those subjects through high school and college on into graduate school. That's what prepared me for being an astronaut; it actually gave me the qualifications to be selected to be an astronaut.

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

You know, I go around the country a lot.

The thing I'll remember most about the flight is that it was fun. In fact, I'm sure it was the most fun that I'll ever have in my life.

I suggest taking the high road and have a little sence of humour and let things roll off your back. I think that's very important.

The experience of being in space didn't change my perspective of myself or of the planet or of life. I had no spiritual experience.
