Here I was into astronomy, and here into anthropology, and there I go into geology. It was much more fun to be able to research and write about whatever I wanted to.

Well, writing was what I wanted to do, it was always what I wanted to do. I had novels to write so I wrote them.

Astronomy's much more fun when you're not an astronomer.

On the other hand, I was very much interested in the way people behaved, the human dance, how they seemed to move around each other. I wanted to play around with that.

People who think about time travel stories sometimes think that going back in time would be fun because you would have all the information you needed to be much more astute than the people there, when the truth is of course you wouldn't.

I just knew there were stories I wanted to tell.
