Too many of us have lost the passion and emotion of the remarkable things we-ve done in space. Let us not tear up the future, but rather again heed the creative metaphors that render space travel a religious experience. When the blast of a rocket launch slams you against the wall and all the rust is shaken off your body, you will hear the great shout of the universe and the joyful crying of people who have been changed by what they-ve seen.

Comic strips introduced me to metaphors. They are pure metaphor, so you learn how to tell a story with symbols, which is a very valuable thing to learn. And I learned that from motion pictures, too, and from poetry. Poetry is mainly metaphor. If it doesn't have a metaphor, it doesn't work.

God, how we get our fingers in each other's clay. That's friendship, each playing the potter to see what shapes we can make of each other.

I believe in having fun first, and along the way, if you teach people, if you influence people, well and good.

Everything is generated through your own will power. You don't have to do anything you don't want to do. This is a democracy. You go where you want to go and do what you want to do.

Suddenly the day was gone, night came out from under each tree and spread.

Do what you love and love what you do. Don’t do anything for money. Everything should be for love.
