Figuring out what to do in my spare time has been a struggle for really my entire adult life. I don't get why it's so hard. For a long time I wondered why I even had to have a hobby.
I can genuinely say that video has been a hobby for me since around 2006, when I bought a bunch of gear, just seven years after I left it as a profession (and I'm freaked out that 12 years have since passed). Since moving to Florida, I haven't done as much of that as I would like, maybe one thing a year, but nothing yet this year. Of course I've considered writing software a hobby as well, but I've struggled with doing that for fun given how much I was writing it for work in my last job. That may reverse now that I'm back to not writing it during the day. I used to game more, but the scope of games that interest me isn't very wide anymore. I've expressed interest in making stuff, with wood for example, but I don't know where to start. I'd like to learn to play guitar or piano or something, but that's another thing that's hard to start.
The thing is, I do like to write. It doesn't require a lot of resources to do so. I mean, I've been writing on this dumb blog forever. I've had some articles published, and various letters to editors. I wrote a programming book once. I wrote some pretty bad screenplays that I never want to look back at. But I really like writing.
In the spring I took Aaron Sorkin's Masterclass on screenwriting, and it was fairly inspiring. I have a lot of stories in me, so I want to getting them out. Writing should be my hobby.
