"Excellence is an art won by training and habituation. We do not act rightly because we have virtue or excellence, but we rather have those because we have acted rightly. We are what we repeatedly do. Excellence, then, is not an act but a habit." - Aristotle
Elder Robert D. Hales said in October 2006 General Conference:
"We must remember that we have control over who we are no matter how difficult the world becomes."
