Blessed & Content

I find myself wondering at times : Is "e;discontentment"e; the by-product of not having enough or refusing to acknowledge what we already have? I have a suspicion the latter is often the case with us humans. If that is our "e;chosen"e; realty here's the ensuing problem : When is enough, enough to say thank you, and do we have the luxury of waiting for that illusive moment to arrive?
