Science fiction, outside of poetry, is the only literary field which has no limits, no parameters whatsoever. You can go not only into the future, but into that wonderful place called other, which is simply another universe, another planet, another species.

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.

It's the Simple things that are really effective. Try to remember that.

The story of my very first sale is the fact that I dreamed up a foolproof paper to cheat an insurance company out of several hundred thousand dollars.

For years, I thought I simply didn't dream. I felt left out. Everybody else had a thing I didn't have.

Writing is a communication.

I find to my mixed astonishment that I do dream, but I didn't know it.
