There are no taboos. Every topic is open, however shocking. It is the way that the topics are handled that's important, and that applies whether it is a 15-year-old who is reading your book or someone who is 55.
A man I know who writes and aspires to be a novelist does very little reading, and he's not that successful. But I think it's because he's like the kid who wants to be a ballplayer and never goes to the ballpark or tries to hit a ball. So I'd say reading is the most important thing that I do, besides the actual writing. I'm always asking as I read, "How did the writer do this? Why do I suddenly have tears in my eyes? Why am I crying?"
Salinger is such a terrific writer; he did so many great things. He is one of those writers that I still reread, simply because he makes me see the possibilities and makes me feel like writing. There are certain writers who put you in the mood to write. In the way a whiff of a cigar will bring back memories of a ballgame on a Saturday afternoon, reading Salinger makes me want to get to the typewriter.
