No problem, really. Even better, reading it now can bring you even better experience and understanding of these themes. I didn’t have it in my school’s curriculum and I read it in my 20s, and I don’t believe I’ve exhausted it at that time in my life. There’s something magic sense in his prose I do feel I won’t find until I have me hairs completely gray. So I find it perfectly okay to reread it and maybe find new thoughts you haven’t got before to enrich thyself. See if you can give it a chance. In some contexts it just huts different.
