Growth doesn't happen where material is easy, and it doesn't happen where material is far above you either. It happens in a specific band in between — close enough to reach with real effort, far enough to actually stretch you. That band has a name in developmental psychology, a well-documented failure mode when you leave it (in either direction), and a live, currently-unresolved version of the same question now that it's possible to just ask something smarter than you for the answer instead of doing the reaching yourself. https://begump.com/research/edge-of-understanding/
