Need and want are not the same things. There are many things I want, things that would make every day life easier, but there really only a few things I need. I don't mean just material things but am using the word in a general sense.
Sometimes those wants seem like they're needs but if I take an honest look at them, in most cases, I can see they truly are just things I want, not that I need. I try not to say, "I want" but to say "I'd really like" instead. I think it helps me see the difference between those wants and needs.
