Digression is the soul of wit. Take the philosophic asides away from Dante, Milton or Hamlet's father's ghost and what stays is dry bones.

As a result of reading science fiction when I was eight, I grew up with an interest in music, architecture, city planning, transportation, politics, ethics, aesthetics on any level, art...it's just total! It's a complete commitment to the whole human race on all the Earth. That's what science fiction is about.

I've never worked a day in my life. The joy of writing has propelled me from day to day and year to year. I want you to envy me, my joy. Get out of here tonight and say: 'Am I being joyful?' And if you've got a writer's block, you can cure it this evening by stopping whatever you're writing and doing something else. You picked the wrong subject.

...I mean, you don't just love people, you must LOVE them with exclamation points.

Hollywood was a good influence because I was madly in love with films, and the films had a direct influence on me.

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.

I’ve often been accused of being too emotional and sentimental, but I believe in honest sentiment, and the need to purge ourselves at certain times, which is ancient. Men would live at least five or six more years and not have ulcers if they could cry better.
