Quality is not an act, it is a habit.

All human actions have one or more of these seven causes: chance, nature, compulsions, habit, reason, passion and desire.

These virtues are formed in man by his doing the actions ... The good of man is a working of the soul in the way of excellence in a complete 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. We are what we repeatedly do. Excellence, then, is not an act but a habit.

We are what we repeatedly do. Excellence, then, is not an act, but a habit.

The quality of life is determined by its activities.
