Whether the degree was worth your time and money, and whether it was interesting, is an entirely separate question, of course.
You don’t need school if you don’t need a degree for your job.

The problem is getting good text books since they’re expensive (when I was in school you couldnt google everything).
I realized I could social engineer my way to free books by appropriating college letterhead, pretending to be a professor, and writing to publishers asking for evaluation copies of books I wanted to read.
Either he had very easy school or picked courses he already knew about or he splits what he learned into "important" (the ones he knew) and unimportant (new stuff).
