Got a good quote for physical therapists?

Apparently being a philosophy student means that people get to ask you to pull quotes out of thin air. I’ve been charged with thinking of something worthy of the motivational whiteboard at work, and I’m brain-dead tonight. Any suggestions? The quote doesn’t have to fit the themes of physical therapy and motivation more than vaguely – the one we have up there now is “To exist is to change, to change is to mature, to mature is to go on creating oneself endlessly.”—Henri Bergson
