Learning when to stop at a satisfactory level is equally hard as learning when to floor it and push against some difficult goal.

I think even 100 honest hours learning something will get you further than you probably need to go, e.g. basic home maintenance stuff that is just 1. find the right youtube video, 2. have the tools, 3. don't be a moron.

god knows that my far beyond satisfactory level of dotfile / config tweaking has probably paid fewer dividends than I'd like to think...
