Suggest a book or series you read/wish you read in your early twenties

I’m currently 19, and am starting to feel that directionless-finding-yourself phase that everyone talks about around this age. I don’t consider it hopeless or depressive, so I don’t think I need anything in regards to bettering my mental health(or maybe I do, i’m 19), but am more interested in something that you read/wish you read around your early twenties that seriously affected/inspired/stuck with you. It also doesn’t have to help me find direction- I’m currently reading LOTR and love it! Id appreciate any popular suggestions that might seem obvious for someone who’s more well-read to have already picked up before. I really want to get more into reading in general.
