The phrase "This too shall pass" and the associated ring story were made popular by Abraham Lincoln in his 'Address Before the Wisconsin State Agricultural Society, Milwaukee, Wisconsin' on September 30, 1859:
It is said an Eastern monarch once charged his wise men to invent him a sentence, to be ever in view, and which should be true and appropriate in all times and situations. They presented him the words: "And this, too, shall pass away." How much it expresses! How chastening in the hour of pride! How consoling in the depths of affliction!Nothing is constant except change which must mean that our best strategy is gratitude for the moment and flexibility for what is headed our way.
