Service is the measure of greatness; it always has been true; it is true today, and it always will be true, that he is greatest who does the most of good. Nearly all of our controversies and combats grow out of the fact that we are trying to get something from each other–there will be peace when our aim is to do something for each other. The human measure of a human life is its income; the divine measure of a life is its outgo, its overflow–its contribution to the welfare of all.
