A good science fiction story should be able to predict not the automobile but the traffic jam.
People ask me how I do research for my science fiction. The answer is, I never do any research.
If you don't care about science enough to be interested in it on its own, you shouldn't try to write hard science fiction. You can write like Ray Bradbury and Harlan Ellison as much as you want.
I let myself flop - so gently, so slowly - into my one real chair and tried to make myself understand that I was on the doorstep of the universe.
I did that for 40 years or more. I never had any writer's block. I got up in the morning, sat down at the typewriter - now, computer - lit up a cigarette.
