Definitely read more of them. I feel like I've read SO many but it turns out I've read just over a third of them. After reading 11/22/63 and On Writing at the very beginning of the year I decided to try to start from the beginning and work my way through all of his books. Got six of the first seven done (I had already read The Stand about three times so skipped it, the others I hadn't read at all) and then I did have to take a break from his stuff. I'm thinking about moving on to The Dead Zone now since I'm between books.
