Dream.

"Gaudi, to his credit, never gave up on his dream, but that's not usually how it goes. I mean, usually, it isnt a speeding bus that keeps the brown pointy, weird church from being built. Most of the time, its just too difficult or too expensive, or too scary. It's only once you've stopped that you realize how hard it is to start again. So you force yourself not to want it. But its always there. Until you finish it its always gonna be."
