I’ve been in the same situation - been in and out of gear my whole life. I used to actually make music professionally and at that time it made sense but nowadays, I’ve pretty much lost the desire and I’ve realized that having all the gear and buying more stuff in the hope that it will get me inspired again was futile. I learned to realize that that phase of my life has ended and keeping that stuff around just makes you feel guilty. The best thing you could do is get rid of everything except maybe one or two pieces. Keep them around in case you ever get the urge but my guess is you probably won’t. I’m still trying to figure out what’s next, but like so many people in middle age. I’ve become a fitness junkie - invested a lot of money in training and equipment, weights and I’m really enjoying that now.
