I don't know, having spent a third of of my life on a single project almost daily, not all that time deliberate and most of it ADD-driven problem avoidance, I ended up inflicting upon myself a personal hell I have only begun to comprehend the depths of. When the interest finally waned I didn't feel I had enough to show for it and every other aspect of my life suffered in ways that will take years to make up for.
At this point all I learned was to fear the next thing, obliterating most of my hyperspecific interests if I'm just going to lead myself down the path of a hermit again another N years. I get out instead but it doesn't make me feel much better anymore. It took too much out of me.

1) the amount of time and effort she devoted to training was simply astonishing to me as a veteran of Div III and club sports.

The problem is that it requires the same effort to verify that the magician isn't just lying, and if there's some way to effortlessly verify the number, then that same method could have been used by the magician ahead of time. To capture the sense of something magical, the reveal has to be immediately obvious, but in a way that (seems like it) can't have been used by the magician to set things up.
