I had that problem after working a year on my open source projects.

Then I went to get a PhD. I thought it would be flexible enough that I could keep working on oss. But there was no time for that. If it had been in a similar field, I could have worked on the oss as part of my thesis, but it was too unrelated

Now I have a PhD and a completely outdated oss project, and do not know what to do next
