I appreciate this methodology for getting stuff done, It's how I do my programming work, but I really do want to just "learn math" for the fun of it, like a puzzle, not make work. I was reading Descartes and he was writing about how the practice of math structured his thinking and I'd like to try to recreate that in myself. Maybe creating a project would be the best way to do it, but that seems like work rather than play to me.
