I've realized today that I've been using my purchase-oriented hobbies (retro games, fountain pens) as a bandage to cover up my lack of progress in my effort-oriented hobbies (learning stuff, making stuff, working out).
The dopamine hit of dropping hundreds of dollars on super fancy new stationary or a rare retro game is very similar, and while the satisfaction doesn't last nearly as long, it's a helluva lot easier to get.
I'm going to cut back on my purchase hobbies in the new year. I know a new year's resolution sounds cliche and tacky, but I generally find orienting lifestyle changes around large events (new year, birthday, vacation) works for me as I feel very rejuvenated after them.
