Everything that happens before Death is what counts.

I don't try to describe the future. I try to prevent it.

I don't believe in colleges and universities.

I'm interested in having fun with ideas, throwing them up in the air like confetti and then running under 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.

I would not see our candle blown out in the wind. It is a small thing, this dear gift of life handed us mysteriously out of immensity. I would not have that gift expire... If I seem to be beating a dead horse again and again, I must protest: No! I am beating, again and again, living man to keep him awake and move his limbs and jump his mind... What's the use of looking at Mars through a telescope, sitting on panels, writing books, if it isn't to guarantee, not just the survival of mankind, but mankind surviving forever!

We should go to the moon and prepare a base to fire a rocket off to Mars and then go to Mars and colonize Mars. Then when we do that, we will live forever.
