Two thoughts on that.
I think we go through stages - where prepping is almost an obsession, then it settles down some and finally it becomes a lifestyle habit or you lose it altogether. My obsession comes back during election years or major disaster events that might affect me locally, but then retreats back to just being a normal part of life. I.e., if I see a sale on something that will store well, I'll buy it and I still try to learn a new skill once a year - in something that interests me. (Making soap, learning to graft plants, etc). Otherwise, I garden & raise poultry mostly because I love it. Like RWS, it's just something I've wanted to do since I was 12. I jokingly say I'm a Pioneer Girl. Even working in the corp world, I always had a small garden where I could, learned to shoot and I read up on some skills, had some storage but not a lot due to marriage, family, etc. I read/listen to books a lot (and rarely prepping books), knit, sew, shop with friends, do church, etc. I have little interest in movies or tv - that's just been me.
Second, I think it's a matter of priorities. Sometimes, priorities change importance in your life. A big house, a cruise, an illness, a vacay to somewhere just because you always wanted to SEE it...and that eats up prep money. It's not a bad thing necessarily, IMO prepping shouldn't be a 24/7 thing just a regular part of your life if possible. If not, then maybe shifting that priority up for a few months a year is all one needs. You don't give up YOU to be a prepper, but I've found the things I've learned about possibilities has changed me a bit.
