"Lack of gratitude is despair."
This message is from a marqee along my morning route, and despite its ringing true, it took me a while to figure out why.
No matter how much we have, without acknowledging its origin, without appreciating its gratuitousness, we cannot hope. Everyone knows deep down that we don't ultimately control our own lives. If what we have is not given by Someone and we can only depend on our own slender efforts, then ultimately there is no guarantee that future events will work to our good.
