Who said "but he that the steerage of my course direct my sail"?

Romeo Montague utters these words in Act 1, scene 4, on lines 113–114. He is still quite depressed about his inability to successfully woo the fair Rosaline, and his friends are trying to get him to go to the big costume party at the house of his family’s sworn enemy, Lord Capulet. He does not feel like dancing or partying, but he feels this strange compulsion to go, as though fate is urging him onward, perhaps even to his own destruction. Romeo uses a metaphor, comparing himself to a sailboat, and he alludes to the fact that he does not feel as though he is in control (or steering) of himself. Someone or something compels him to attend the party.
