On and off over the last 15 years or so.

Only recently have I become much more comfortable & able to resolve things without resorting to search, stackoverflow etc.

The turnover point was the day I finally learned vi & cron so I could fiddle with an old Buffalo NAS, that was long out of support, riddled with security holes, and offered only very limited tooling.

Was a great learning experience, but it didn't pan out the way I wanted. So it runs Debian now, supports modern protocols, and continues to serve. Amazing what you can keep in service when you try.
