Yoda: ConcentRAAAAAATE!
Luke: We'll never get it out now!
Yoda: So certain are you. Always with you it cannot be done.
Luke: Master. Moving stones is one thing, but this is totally different!
Yoda: No! No different! Only different in your mind! You must unlearn what you have learned.
Luke: Alright. I'll give it a try.
Yoda: No! Try not! Do. Or do not. There is no try.
