Leah Zhang, the certified Alexander instructor who is co-teaching my current Advanced class at the moment, sent a great excerpt from a book called The Body Speaks by Lorna Marshall to my current students. I have picked out an excerpt from the excerpt that I thought was really valuable.
People sometimes confuse experiencing with learning. Experiencing an exercise means you have encountered it and understood it. Learning means that you have repeated it so often that you can reproduce its function at any time, anywhere. It is no longer something you have met once and found interesting; it is something you own, that you have claimed and can easily repeat. (And remember, the business of performing is repeatability. Every night on stage you must be able to repeat and reproduce a vivid performance. When filming, you must be able to repeat a moment of great sensitivity again and again, until the director has all the takes he or she wants.)
“We are what we repeatedly do. Excellence, therefore, is a habit, not an act.” –Will Durante, paraphrasing Aristotle
