One of the most important concepts from Mastery. A person’s life’s task is the specific calling, or vocation, of that individual. It is what that person is designed to do or express in life – a reflection of his or her deepest interests, talents, and yearnings. Greene advises using one’s life’s task as a way to guide one’s decisions and interests. To discover your life’s task, look at activities you used to love as a child or things that deeply interest you if you read about or see it.
