I've been programming for 30+ years now, but I've always been fine with command line applications. Only recently I started getting into Qt to add a UI and turn my stuff into a real desktop application. It's been a real steep learning curve but I'm finally over it more or less.
Anyway I posted a screenshot of my application on LinkedIn, and mentioned it would be free and open source. I got HUNDREDS of comments from "LinkedIn-type people" all big name engineers that wouldn't HIRE me for anything but either made comments like "looking forward to integrating this into our workflows" or "not the first time someone tried to do this..."
Either way, instead of feeling motivated, I got the worst feeling that I'm doing all this work and people are either going to just take advantage of it and get the credit for "finding" it, or criticize it simply because it's not for them.
It bummed me out so bad that I stopped work on it entirely for like a month.
Anyway I finally came to look at it the way you mentioned. What I LIKED was the process of learning Qt and seeing my old programs come alive.
So instead, it's my "project car" now. I build it up and tear it down all the time. Totally redesign the data models just to see what advantages different designs can give me. Try make my own graphical views. Try implementing language translations.
It's been "finished" for a while now but I probably have five completely different-under-the-hood versions of it and THAT is what has been fun.
I use it constantly all day at work and I never mentioned it on LinkedIn again lol
