I used the term "want" because my definition of need is quite narrowly defined. To me, "need" is survival (Shelter-Water-Food). Everything else is "want."
Ahh, semantics...
I define 'need' as need, same as eveyone. But, the similarities between us stop there. I define 'want' as an interest in obtaining something unecessary that was once possessed but that is not presently; and I define 'desire' as an interest in obtaining something never before possessed, regardless of whether or not it is necessary. I think someday I will further distinguish between two or more kinds of desire.
