what is the difference between need and desire... I know there's the basic needs of survival and I know the difference between needing transportation and desiring a 67 shelby mustang 500 gt.  What i mean is what do we need for contentment or is that even a need.

 some of the things that are important to me. Self respect, feeling a sense of accomplishment, love, companionship, laughter, being valued/loved by at least one person, hope, forgiveness both for myself and others, belief in God, faith, gratitude, sense of history and shared experience, expression... what of these are needed for contentment though?

feeling oddly philosophical and analytical without much to focus it on obviously.
