22. 'That Is Why You Fail' ('The Empire Strikes Back')
A dejected Luke tries to raise his X-Wing fighter out of the swamps of Dagobah using just his mind, but gives up when he can’t budge it and questions whether he will ever master the ways of the Jedis. Cut to the tiny Yoda, who raises it himself in what becomes the saga's key exchange about the power of faith in the Force. Luke: "I don't believe it." Yoda: "That is why you fail."
