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.

I had immediate success in the sense that I sold something right off the bat. I thought it was going to be a piece of cake and it really wasn't. I have drawers full of - or I did have - drawers full of rejection slips.

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.

The Berserkers have been with me for about forty years, and we're not done yet.

The comments I most appreciate come from ordinary readers who've happened on one of my books at some time of stress in their lives, and who actually credit the book with helping them through a bad time. It's happened a few times in forty years.

I wouldn't like to just do one story or one type of stories all the time.

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