What has this hobby taught you?

[Herc Driver]

First and foremost...that I needed glasses.

Then in no particular order: history, economics, soldering, glueing tiny details onto Nscale engines, that medical clamps and tweezers work really well with Nscale, budgeting, patience, frustration, reward. And that all the skills I learned in kindergarten proved to be the most useful...like glueing, modeling, cutting, and imagination.
