The transformative power of good habits, and Aristotle’s principle that practice makes perfect, rests on our essential spiritual purpose. The goal of man from the start is to be happy, and “it is virtuous activities that determine our happiness.”25 As human beings, we have an inborn disposition to virtue; if we want to cultivate that disposition, which most of us do (who really revels in being evil?), we need to cultivate the habits that go with it.
