“Serving a cause means immersing yourself in it. It’s what you have chosen to devote yourself to. It’s not a hobby, a distraction, an amusement, a diversion, a way of passing your time. It’s your actual identity ... the one you have consciously and deliberately chosen for yourself, in exclusion of all others. It hasn’t been chosen by your parents for you, or by your friends for you, or by your community for you. You, no one else, has made the commitment. It’s your choice, your decision. It reflects your worldview, your chosen idea of how to lead your life. Your sacred cause is the meaning of your life, so you had better get it right.”
