I think everyone has their own amount of upgrade-itis to get through before they come out the other side. It took me about a decade of buying every (EVERY) last major and minor update from Apple, Nikon, Campagnolo, Fat Chance, Yeti Cycles etc.
Eventually, you can end up looking at the objects you’ve acquired as a collection you’re actively curating, and when you see how inexpensively you can pick up an older favorite model you parted with, just to put on your shelf... & then find that old classic still works as well as it ever did, has features or qualities the new ones don’t have, and… and then there you are, off the upgrade train, delighted that you can choose to acquire and use the finest things you love rather than the newest.
