So if I were to take your advice (and honestly, I mostly do run like that) it means a lot of time spent doing something ephemeral with no real lasting benefit. I think your last point applies to me. I wish I could summon enthusiasm for projects rather than hobbies.
I like games so started doing a Unity course, it was fun, but then I got bored and stopped. No real reason, I think something else just caught my eye and it's hard to go back.
I want to learn marketing automation so I installed Mautic but haven't gone much past that. The plethora of options (what feature to try first?) is paralysing.
I help out with a Wordpress site and think making plugins would be neat, so I made one to help test some stuff, and that scratched the itch and now I don't really feel like doing it anymore even though it would be useful (and maybe profitable?) to learn.
These were all fun and interesting I just seem to lose interest very quickly (a few days) and want to do something with more novelty. Probably the most productive way this manifests is cooking, at least we get to eat a bunch of new recipes. Today I'm making bread but hopefully I can also finish setting up this email series :)
Exploring more interests and different ways of doing things changed a lot of things for me.
Things can also change when you know how to do things in a way that aligns with you. I used to hate cooking, but found my take on it.
