There's a big overlap with the people you meet at the fantasy and science fiction cons.

I guess if one set of my books was selling like Stephen King's, and the other wasn't selling at all, editors would want me to do the ones that sold like Stephen King's. But they seem to be willing to let me pick what I want to do next.

If people ask me for the ingredients of success, I say one is talent, two is stubbornness or determination, and third is sheer luck. You have to have two out of the three. Any two will probably do.

And what we know, or think we know, about the universe of space and time is changing very quickly.

I finally decided one day, reading science fiction magazines of the time, I could do at least as well as some of these people are doing. So I finally made a serious effort.

I started writing seriously about 1960, at the fairly advanced age of 30.

I don't know why a computer game can't be an art form just as a puppet show or an opera is. I'm still interested in computer games as something I would like to work on someday.
