I'm pretty sure I'm being wasteful for really dumb reasons
Why do you think you are wasteful?
Some of my reasons were that I could buy more expensive shoes, and clothes
Everybody makes mistakes, it is good that you realize that and make changes. It could change your life for the better.
I will limit myself on buying things that make me happy
Remember there is nothing wrong with treating yourself every once in awhile but yea just cut down on the spending.
