Another strategy I use in my seeking to make fewer purchases so that I can enjoy life more and be less blocked by too much stuff and bills is this…
I put things on a list.
If I want something, I’ll add it to the list.
I look the list over once a week and see if anything that’s been on the list still appeals to me.
When I realize that getting another (usually) physical item, and yet I’ve made do without it, I realize I don’t really need to but that item.
