We are what we repeatedly do. Excellence, then, is not an act, but a habit. (Aristotle, 4th century B.C. Greek philosopher)
Over time our habits of work, word, and activity reveal quite clearly who we really are—or, at least what our real interests are. The more we repeatedly pursue certain activities, the more we identify with them, and they reflect our character and nature. Perhaps Aristotle was suggesting that if we want to be excellent in our endeavors, we must pursue worthy interests.
Whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things (Philippians 4:8).
