People who take books on sex to bed become frigid. You get self-conscious. You can't think a story. You can't think, "I shall do a story to improve mankind." Well, it's nonsense. All the great stories, all the really worthwhile plays, are emotional experiences. If you have to ask yourself whether or not you love a girl or you love a boy, forget it. You don't. A story is the same way. You either feel a story and need to write it, or you better not write it.

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.

My passions drive me to the typewriter every day of my life, and they have driven me there since I was twelve. So I never have to worry about schedules. Some new thing is always exploding in me, and it schedules me, I don’t schedule it. It says: Get to the typewriter right now and finish this.

The very first experiments with building rockets and firing them off were carried out by students at Cal Tech in 1937, '38 and '39. And later these people put together these jet propulsion labs in Pasadena and wound up sending aircraft and spacecraft to the moon. So it all began very primitively with love.

There must be something in books, something we can’t imagine, to make a woman stay in a burning house; there must be something there. You don’t stay for nothing.
