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

Advertising reaches out to touch the fantasy part of people's lives. And you know, most people's fantasies are pretty sad.

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.

I don't think the scientific method and the science fictional method are really analogous. The thing about them is that neither is really practiced very much, at least not consciously. But the fact that they are methodical does relate them.

If you don't care about science enough to be interested in it on its own, you shouldn't try to write hard science fiction. You can write like Ray Bradbury and Harlan Ellison as much as you want.

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.
