How to rewire your brain to enjoy other things than findom again?

I’ve made many quitting attempts over the years and I’m trying to give it a serious shot again. My main issue with staying away from findom has been that I hardly find anything nearly as exciting anymore. I assume my brain was rewired long ago, I fetishized something that shouldn’t have been and I rewarded and solidified certain neural pathways with repeated behaviors. I have been forcing myself to “enjoy” more ordinary things, but that usually ends up with me browsing findom-related content. If anything, it feels like I should get myself going with findom stuff, and finish on something more “normal” to somehow link it to the dopamine hit. Anyway, how do you manage to pull that off to go back to enjoying more conventional things, and how long does it take? Any advice in general is welcome. I’ve been really struggling and I hope I can use the momentum of the new year to build stronger motivation and discipline.
