In my opinion, wanting and needing something are two huge differences and i think  thats a big misconception people in the society don't understand, Its like seeing a pair of shoes go on sale at a store, do you actually need them? probably not. But say its winter time and you need a jacket because you live far from your school or work and you walk to your destination, thats the difference. i also buy a lot of things too, and i don't really need them and its sort of a problem that i need to fix but my mother keeps my debit card so thats how i stop buying things, because she also knows i have a problem.
