I am debt-free thanks to YNAB and now when I buy something big, I really feel it. Before I buy something I always go to YNAB and see what it feels like to empty a category or move money away. If it doesn’t feel good, I’ll usually sleep on it a few nights until I feel comfortable making the purchase. A lot of times I’ve just outright skipped the purchase!
This is a good way to phrase it, I also feel the “weight” when I purchase things. I think it really helps to help consciously spend rather impulsively and thoughtlessly buy things.
