I think with acting, since I became an actor... I, as a person, have become more confident and I have really come out of my shell somewhat... and back to myself, you know.

I played rugby most of my life and then I switched to snowboarding, which provided me a lot of inspiration.

I like to run on the beach. It's a different exercise as well when you're in sand, a different kind of training.

For lack of a better word, acting is therapeutic. You really are breaking down barriers, exorcising demons and finding more out about yourself.

I think any kind of hiatus one takes in an artistic journey is going to make a huge difference. The pause will inform the choices that you make.

There's a perspective that I've gained as an astronaut that I didn't get from my science activities. In my science activities, I learned by the seat of my pants. Spending 17 years as an astronaut, I learned the NASA formalism of systems engineering as if my life depended on it. Literally.

Surely it is time to examine into the meaning of words and the nature of things, and to arrive at simple facts, not received upon the dictum of learned authorities, but upon attentive personal observation of what is passing around us.

Hope is a feeling that life and work have meaning. You either have it or you don't, regardless of the state of the world that surrounds you.
