Education is a nice side effect sometimes but yeah, I don't know how you could reach any other conclusion. If you're motivated to learn for learning's sake, college is an annoying slog that you know you don't need post-millenium. I literally left college early and started making money instead of spending it, because I got tired of demonstrating to my professors that I already knew everything they were teaching and that it'd be a waste of time for me to come to class.
Or maybe you chose to waste your time because you treated college as a way to get a piece paper instead of as the only time in your life when you are surrounded by experts who will spend an hour a week answering any questions you can think of.
