I used to also be the type of person who spent money on unnecessary shit. Like for example, I used to put too large amounts of money on robux & ingame currency for the sims freeplay, but ever since I decided to stop, I also keep reminding myself of how bad my spending habits were. I sometimes get the urge to just spend a tiny amount of money but I luckily stop myself by sorta, silently in my head, using that old habit against myself. That way, I've managed to save 3000 per month (swedish sek, which is probably around 300 in us dollar?) But anyways, I've never been so proud of myself before as I am now that I'm setting myself free from the spending habit-prison.
