The only time I really regret buying what I like without strong guardrails is that I can't have everything out at the same time, and I'll sometimes just have an existential crisis of "I truly love all this stuff, but sometimes some of it is stored in a box in my studio." But also one of my huge joys is taking a Saturday afternoon and swapping out my Marvel or Joes office display. Hey, Night Force for a few weeks! Or Oops All Animal Companions. Or whatever. So I feel less like hoarding and more like how my mom (oh no) is super into holidays and seasons and will completely swap out her decorations in the house every other month to match the time of year. I think I just figured out where I got it and now I wish I had a therapist on call.
Also, not just the house fire, I have gone minimalist twice in my life - lost everything in a house fire, and then got RID of everything when I moved to Ireland. Now that I'm settled, I'm getting older, I have a house of my own, and in this economy I'll probably DIE in this house... I'm more maximalist now, I guess. I did the own nothing thing, it was cool, now I'm greedy. (I also don't have kids, so... expendable income.)
I think the Classified line is what I restrict the least though.
We also, collectively, as a board, bully TF out of you to buy stuff. Specifically you. All the time.
Now if I could just get some of that self control to bleed over into fitness.
This is how I know it's not a discipline thing for me. I work out 60-90 minutes every day, I plan my workouts if I'm on vacation, I militantly lock down time in my work schedule to lift and run. If I needed to discipline my buying, I would. (My partner actually WANTS me to buy action figures because it's the first time she's ever spend money on myself. Usually I just save money for when there's a house disaster or worrying about one of us losing our job. We had three huge home repairs this year I paid out of pocket for, so I know I've got discipline to save money when we need it. It's just taken 48 years to have income to not stress out about a 28 dollar toy.) I've got crazy self-control. Toy collecting is the one place I don't actually beat myself to a pulp over not enjoying life.
