I actually have worked on a few open-source projects but I never submitted my patches... then I forget about them and they get lost to time lol. On stock OpenBSD (which I run), my desktop PC's audio is kinda broken (long story, can link you a post I made about it if you're curious) so I had to patch the OpenBSD kernel Intel HDA (corpo acronym but the last letter means "audio") driver to make it work properly (had to add a whole new mode of operation for what I think is probably broken hardware, like my motherboard manufacturer fucked it up). I'm still maintaining that patch on my own lol, I need to submit it.

It's good advice and I don't mind, I'm just maining untreated ADHD rn, maybe that's why I don't do these things

As for my own projects.... these grand and often probably ridiculous ideas for software (recent example: video game as a filesystem) come into my head and I hack on them obsessively for a while and never finish them because of the scale :(
