To be worst, The lowest and most dejected thing of fortune, Stands still in esperance, lives not in fear. The lamentable change is from the best; The worst returns to laughter. Welcome, then, Thou unsubstantial air that I embrace! The wretch that thou hast blown unto the worst Owes nothing to thy blasts.
William Shakespeare (1564–1616), British poet. King Lear (IV, i).
