All's Well That Ends Well — William Shakespeare

All's Well That Ends Well is a play by William Shakespeare written  between 1601-1608. Originally classified as a comedy, though now often counted as one of his problem plays, so-called because they cannot be easily classified as tragedy or comedy.
The name of the play comes from the proverb All's well that ends well, which means that problems do not matter so long as the outcome is good.
