Not the OP, and it's definitely not my style, but some people really like taking classes. They love the environment and energy that a university life gives them. I've known one or two people who have spent decades just taking classes (and accumulating degrees).
This is really weird to me but to each their own. I think it's partially because of ADHD but I really hate doing HW/writing essays that I feel are useless, which tends to be pretty common in uni.
