Choosing and developing great habits puts you on the road to achieving and maintaining excellence in your life.
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. Moral excellence comes about as a result of habit. We become just by doing just acts, temperate by doing temperate acts, brave by doing brave acts.
We are what we repeatedly do. Excellence, then, is not an act, but a habit.
