I repeat Sturgeon's Revelation, which was wrung out of me after twenty years of wearying defense of science fiction against attacks of people who used the worst examples of the field for ammunition, and whose conclusion was that ninety percent of it is crud.

Inner space is so much more interesting, because outer space is so empty.

The first writing I did was short short stories for a newspaper syndicate for which I was paid five dollars a piece on publication.

Writing is a communication.

Anybody can do anything he wants to if he wants to do it badly enough.

Fiction is very important to me. It's what I do, it's what I do with my life.
