Don't worry, it's not a rule that you can't become interested in new things past age 24, haha. Of those I've only read Moby Dick, As I Lay Dying, and Crime and Punishment, all also in my teens or early 20s. Loved Faulkner, liked Dostoevsky, did not love Melville. There are a lot of, like, musings on whale anatomy in it? Which makes it pretty hard to get through, though it's certainly a very grand and thought-provoking book regarding what it says about the nature of our lives. I agree with him certainly on reading as much as you can, heh.
