I have a very irregular work schedule, resulting in a lot of free time punctuated by periods of intense crunch. It's not unusual for me to have a few weeks at a time just empty of work.
I post my hobby/sidegig tabletop commission projects, since I'd have been working on them even without Lemmy. Then since in real life I come across many odd things in my traveling, I'll make sure to snap some photos.
Then I just have a daily habit of browsing certain sites and feeds related to various Lemmy communities and linking to Lemmy whatever catches my eye.
