My Cup Runneth

This is part of a theological discourse, but I would like to view it from a secular stance. When one's proverbial cup is full it refers to abundance of any kind such as, peace, joy, contentment, monetary wealth, simply the act of caring for others via volunteering and sharing one's intellectual currency.

Most importantly, I think there is an overarching sense of living and being in the overflow.So what do we do with it? Especially, if there is plenty to spare and share?
