I've had the same thought, but on the other hand, would you really feel ready for math and physics at 30 if you hadn't spent years struggling with it at 18-24?

I've had the same thought, but on the other hand, would you really feel ready for math and physics at 30 if you hadn't spent years struggling with it at 18-24? Maybe the only way to develop the maturity to feel ready is to dive in and struggle with it anyways, even when you don't feel ready.
