Want = Longing = Can survive without it
Need = Essential = Cannot survive without it
I think of it this way: if I need something, it's something I can't live without - like I need to have a place to live, I need to have a job to pay for the place to live, I need to eat and drink so I won't starve or get sick, I need to pay bills so that collection companies don't seize my bank account; I may need to see a doctor perhaps. What I want are things which if it came down to it, I don't really need, I just desire it, but it's not imperative that I have it.
It's not. Needs consist of food, shelter, water, air, sun and the natural things.
Wants consist of something much deeper, that which makes you an individual.
They lack to separate the necessities from the priority's to determine the essential elements.
Because people think they want things that aren't needs.
