It was really just pushing frontiers, that's all we were doing.

As a species, we've always been discoverers and adventurers, and space and the deep ocean are some of the last frontiers.

I'm mad, you know? I don't think of retiring at all.

I've got to admit it's getting better. It's a little better all the time.

Think globally, act locally.

I think I always had a musicality, and I think I could tell a good song from a bad song. And I would appreciate hearing something that was new to me.
