 The other way that people have ideas is walking. The great poets of the English countryside would walk for miles and miles, and they would find ideas would come flooding to them. And I find the same thing. If you walk, after about half an hour's walk, I find myself having ideas. And there are other quirkier ideas that people have used in history. Vladimir Nabokov, the writer, used to find sitting in a parked car after a long journey, he'd have ideas.
