A jewel is hidden in this hard season, as the ugly toad was said to wear one in its head. Find what the difficulty is teaching you and keep it when the season ends.
William Shakespeare
As You Like It, Act 2, Scene 1
Sweet are the uses of adversity,Which, like the toad, ugly and venomous,Wears yet a precious jewel in his head;William Shakespeare · As You Like It, Act 2, Scene 1
