Equilateral Triangle

My sponsor taught me that Alcoholics Anonymous has three legacies: the who, the how and the why. They are called recovery, unity and service, and they are set like an equilateral triangle. Confused, like many a newcomer to AA, I thought, "Hey, I'm not drinking, I'm calling my sponsor on occasion, I'm making coffee for my Wednesday night home group meeting. What more do they expect me to do?"
