“Unlike success and failure, contribution has no other side. It is not arrived at by comparison. All at once I found that the fearful question, ‘Is it enough?’ and the even more fearful question, ‘Am I loved for who I am or for what I have accomplished?’ could both be replaced by the joyful question, ‘How will I be a contributor today?’”

—Rosamund Stone Zander and Benjamin Zander, The Art of Possibility
