The difference between "want" and "need" is pretty simple, until you set yourself loose in a store. When it comes to owning or acquiring certain things, us people/humans would often use the term "want" and "need" indistinguishable. I think a need is generally referred to, in economics, or as something necessary for a person to survive. Subsequently, a "want" refers to something that a person desires, either right now or in the future. How I picture a "need" is having a roof over your head, enough food and water to maintain your health, and basic health and clothes. But usually everything goes beyond this. Like getting a big house name brand clothes, fancy food and drinks and maybe a new car is a desire for pleasure. Personally, we have to start appreciating what we have and not show off because we have the tendency to always get the latest new anything.
