"Just as our fingerprints are one-of-a-kind, so is our identity. Each of us is a once-only articulation of what humans can be. We are rare, unmatched, mysterious. This is why the quality of openness is so crucial to our self-discovery. We cannot know ourselves by who we think we are, who others take us to be, or what our driver's license may say. We are fields of potential, some now actualized, most not yet."
