In my junior year of high school, I was in AP Literature, and I had to read Doctor Zhivago, Doll's House, Antigone, and several other books and plays I can't remember. I hated it so much it turned me off casual reading altogether.
For my senior year, I dropped down to regular literature. That year I read One Flew Over the Cuckoo's Nest and Slaughterhouse-Five. I loved both of them, with Slaughterhouse-Five being the favorite book I've ever read. If I hadn't dropped down to regular literature I wouldn't have read those books and I probably would've given up reading as a hobby.
