Mine is video games. Like, I’ve sworn to myself that I was going to cling to that until at least 10 or 15 years while I still have the cognitive ability to play them. But it’s mid-30s and they say the 30s is generally where your love for video games go to die unless you’re in the industry or having some working part involving games.
I’m having a harder time picking up a controller and getting excited for any game. I know I’m isolated by choice which is part of the problem, but, I can’t even get that worked up for nostalgic games that I grew up with.
Environmental/political activism. I used to be pretty active in local groups. When I had kids, I bowed out to help my spouse. Now that I have time again, I feel unmotivated - news is just so damn depressing.
