Isaac AsimovWhen I sit down at the typewriter, I write. Someone once asked me if I had a fixed routine before I start, like setting up exercises, sharpening pencils, or having a drink of orange juice. I said, "No, the only thing I do before I start writing is to make sure that I'm close enough to the typewriter to reach the keys."
