People as me how I do research for my science fiction. The answer is, I never do any research.

I did that for 40 years or more. I never had any writer's block. I got up in the morning, sat down at the typewriter - now, computer - lit up a cigarette.

In terms of stories I would buy for a science fiction magazine, if they take place in the future, that might do it.

They were two lovely choices. One of them meant giving up every chance of a decent life forever...and the other one scared me out of my mind.

The big new development in my life is, when I turned 80, I decided I no longer have to do four pages a day. For me, it's like retiring.

What were we doing here? Traveling hundreds or thousands of light-years, to break our hearts?

You can't really predict the future. All you can do is invent it.
