I never expected a money success. In fact, I never even thought of commercial publication when I wrote The Hobbit back in the Thirties. It all began when I was reading exam papers to earn a bit of extra money. That was agony. One of the tragedies of the underpaid professor is that he has to do menial jobs. He is expected to maintain a certain position and to send his children to good schools. Well, one day I came to a blank page in an exam book and I scribbled on it. 'In a hole in the ground there lived a hobbit.' I knew no more about the creatures than that, and it was years before his story grew. I don't know where the word came from. You can't catch your mind out. It might have been associated with Sinclair Lewis's Babbitt. Certainly not rabbit, as some people think. Babbitt has the same bourgeois smugness that hobbits do. His world is the same limited place.
