In 1957, Dag Hammarskjold, a Swedish economist and diplomat who served as the second Secretary-General of the United Nations, wrote in his private journal Markings:  

Each day the first day.  Each day a life. Each morning we must hold out the chalice of our being to receive, to carry, and give back.  It must be held out empty – for the past must only be reflected in its polish, its shape, its capacity.
