There were really two components to it I valued - the inherent interest in the topic itself of course, but also the sense of community and recognition you got as you dove deeper and created cooler things to share with people. At some point the second overtook the first, and I internally started to value the outcome or reaction to something I would create more than the satisfying pursuit of making itself. Doing a thing wasn't valuable unless it would be acknowledged by some group of people. It's been a long process trying to get rid of that mindset and I'm still not done, and has caused a lot of anxiety and questioning my interest in the hobbies I love.
A lot of the questioning has been driven by the absolute saturation of my online feeds. The algorithm can so quickly figure out the type of stuff I like and show me so much of it that it begins to start feeling meaningless in 10 minutes of scrolling - deconstructing that value system in real time (and I guess technically helping? hooray for accelerationism). If there is so much out there, what am I supposed to create that could add to the pile in a meaningful way? It really takes a lot of effort to sever yourself from the algorithmic mindset and remind yourself that you got into it because you like doing the thing.
Not to mention the second order effects, like the ancillary feelings of guilt that show up because I start questioning why I want to avoid seeing things about topics I supposedly enjoy. Part of it is personal flaw - I find it difficult to see something cool without feeling some imperative to figure out how I could do it myself. When I don't want to feel bothered, I'm driven towards more mindless consumption that doesn't run the risk of reminding me that I should be doing something. I feel I would be much happier engaging in the hobbies I have if I was a bit less aware of everything related to them going on in every part of the world, and the algorithm is a big culprit in that. Detaching from it is not just hard because "phone feels good", but also because it means completely giving up on the value system I grew up on, where you could know if you were doing something meaningful if it got attention from other people in the communities you wanted to be a part of. "Attention" has been too commoditized at this point to use it as a fulfilling indicator of return (but unfortunately, some people have to play this game if they want to support a living off a creative endeavor - at least I can ignore that part because I just make music or do creative coding as a hobby).
