I'll tell you a story:
King Solomon ordered his minister to find that which would make a sad man happy and a happy man sad. The minister traveled the kingdom for six months, the night before it was due he wearily asked a peddler in the old city of Jerusalem if he had such an item. The peddler told him to wait and disappeared. He came back with a ring, engraved "this too shall pass". Upon receipt, King Solomon smiled. This too shall pass. Perfect.
