If I were to do stuff during quarantine, I would take online college classes, work on my comic (and a few websites), and practice driving to get my license. At least with me practicing driving, I get to go out a bit more.
EDIT: I just got word yesterday evening that I'm not supposed to drive during the lockdown or evening hours, unless you're going to necessity places, such as grocery stores. Tough for me.
Still annoyed that I'm working in a grocery store since 3 years ago (2017), but at least I'm making money.
