This is why I'm anxious to get to softball practice every week-- because I've spent time at home focusing on my own techniques, comparing with pros, watching youtube videos, trying things out. Eventually, I'm just ready to see if I'm more successful in a game-like environment. Some others also exhibit this constant series of small improvements; others seem to have decided that they're "done learning," and now they've stagnated. To my eye, that seems a lot less fun.
Maybe I should practice that more in other areas of life.
