Recently I occasionally manage to just not let go of a challenging task, even though I would have other plan, which means I mess those up for myself, like today. Which is even more infuriating on top of the fact that thing I was working on should just fucking work.
I have set an alarm now to “get the fuck away from work” on weekdays, maybe that helps.
… which also leaves me int he mood to so fuck all that could usually be maybe fun sometimes. Like vr shenanigans are a constant stream of jank only alleviated if creatures I know are around (so just the next infuriating problem to bang my head against), focussing on other media (reading, watching something) won't work because my brain won't fucking let go of trying to solve the thing, going to Aikido is the thing I fucked up myself, etc…
… ended up catching up on a story I was a dozen chapters behind on, which helped. It was no setup effort and predictable results compared to the other options more at the whims of external factors.
(but I also only did this after I still read some
of the source code related to my problem).
