This could be work or recreational related. Anything you’ve done that you sit back and go “hell yeah I did that”. I’m typically wary of working on cars because I have big hands and no auto specialty tools. But, I was able to make a pretty involved (for me) repair last week and I’ve felt really great about it since. What about you?
Got my own single user PieFed instance running on YunoHost before it was ready for production. Lots of testing, multiple failures, but I got it running in the end and it works great.
