Science fiction is really sociological studies of the future, things that the writer believes are going to happen by putting two and two together.

The psychiatrist wants to know why I go out and hike around in the forests and watch the birds and collect butterflies. I'll show you my collection some day.Good.They want to know what I do with my time. I tell them that sometimes I just sit and think. But I won't tell them what. I've got them running. And sometimes, I tell them, I like to put my head back, like this, and let the rain fall in my mouth. It tastes just like wine. Have you ever tried it?

Heaven is a house with porch lights.

There are certain kinds of people who write science fiction. I think a lot of us married late. A lot of us are mama's boys. I lived at home until I was 27. But most of the writers I know in any field, especially science fiction, grew up late. They're so interested in doing what they do and in their science, they don't think about other things.

In your reading, find books to improve your color sense, your sense of shape and size in the world.

I don't like the kind of writer who's out to change the world and beat up on people for their own good. Stalin did that and Hitler did that, and to hell with them.

I am a dedicated madman, and that becomes its own training. If you can't resist, if the typewriter is like candy to you, you train yourself for a lifetime. Every single day of your life, some wild new thing to be done. You write to please yourself. You write for the joy of writing. Then your public reads you and it begins to gather around your selling a potato peeler in an alley, you know. The enthusiasm, the joy itself draws me. So that means every day of my life I've written. When the joy stops, I'll stop writing.
