There are countless ways I feel different from the people around me, but spending habits is a big one. I never had the urge to start buying things when I got money. I’ve just always saved it. Even as a kid, I had a chest with a lock on it where I kept all my savings. I was always the one people borrowed money from and paid back with interest.
Now as an adult, I find it even easier not to go on a spending spree when I get a large lump sum of money from somewhere, because getting more money doesn’t really enable me to buy something I couldn’t have bought before. Even when I do treat myself to something, it’s usually BIFL quality, so once I have it, I never need to buy it again.
I guess it’s worth noting that always being alone with no one to spend the money with helps too.
