Good advice, even tho saying "you don't need this" is relative tho. Sure thing, the only things we legitimately NEED is basic needs, the rest is relative and depends on the POV. For example for me, I needed to upgrade my computer recently, maybe other person could have said "you don't really need a better graphic card" but in my POV i really needed it so fuck it, I bought a new one.
Yes, even though I agree that spending on things that make you happy time to time isn't bad but there is a limit to the extent. I usually only spend my money on necessary things and save the rest for emergencies or for future plans.
