I want to be working on a... something, an anything really. But, I'm stuck. I don't know where to begin or how to start.
Maybe it should be a web project, I've always wanted to sell a few themes or write/create an instructional series for Grav. What about all of that "Open Web" business, perhaps having a go at integrating ActivityPub or MicroPub endpoints to your site might fit the bill.
No, maybe you should do more open-source and Linux community projects. You've been having a good time participating in that community, so now might be the time to give back. Should you start creating more issues, helping provide support/documentation to a project, or maybe pick up a light programming task. You've got the time to get that started, right?
Wait, what if you just went outside and practised taking more photos, or went to the library and took out a stimulating read? Oh, you could catch up on that novel everyone's always on about. What about the classincs? How will you ever show your face on the Internet again without understading Aristotle, or Nietzche? (To be fair, you have had read a few works by both, not that you remember or understood well enough to be telling people about.)
You know what, why don't you do what everyone would have guessed in the first place? Why don't you just do none of the things you wanted to, write an angsty blog post and feel bad.
There, that's better, isn't it?
