I struggle with spending a bit too much as well.
Recently I have been doing a better job of this. I have been thinking about how budgeting is similar to losing weight. I’ve been working on both and it comes down to not eating that extra snack... or not buying that one extra little thing... Simple but very difficult for me to do in the moment.
I don’t go to the mall but I do like to shop online. I think it’s a way of distracting myself from boredom or feeling sad.
