As human beings, our greatness lies not so much in being able to remake the world - that is the myth of the atomic age - as in being able to remake ourselves.

I wanted to be a teacher. I love children, so I wanted to deal with children. Then I wanted to be a veterinarian. But by the age of ten or eleven, when I opened my mouth and said, 'Oh, God, what's this?' I kind of knew teaching and being a veterinarian were gonna have to wait.
