When you're all alone out there, on the end of the typewriter, with each new story a new appraisal by the world of whether you can still get it up or not, arrogance and self-esteem and deep breathing are all you have. It often looks like egomania. I assure you it's the bold coverup of the absolutely terrified.

I know that pain is the most important thing in the universes. Greater than survival, greater than love, greater even than the beauty it brings about. For without pain, there can be no pleasure. Without sadness, there can be no happiness. Without misery there can be no beauty. And without these, life is endless, hopeless, doomed and damned. Adult. You have become adult.

For the first time we have a weapon that nobody has used for thirty years. This gives me great hope for the human race.

You're a writer. And that's something better than being a millionaire. Because it's something holy.

I made as many mistakes as anybody else. I sound as if I'm an egomaniac, and I suppose in some ways I'm filled with hubris because I know how good I am at certain things. But other things, I can't do at all. I can't draw.

Star Wars is adolescent nonsense; Close Encounters is obscurist drivel; ‘Star Trek’ can turn your brains into puree of bat guano; and the greatest science fiction series of all time is Doctor Who! And I'll take you all on, one-by-one or all in a bunch to back it up!

I cannot pay attention to what people say about my work. For me, personally, I am just this shards-and-ashes human being, who really gets upset when someone says something bad about me. If it's true, I cop to it. If I have any good qualities, it's that.
