Query: This book won't change your life

The On-Purpose person is written as a story. A seeker encounters a series of on-purpose people who give him advice and guidance about how to change his life. Essentially he is told to prioritize his "wants" and decide on a "core purpose" for his life. The wants are of course subordinate to the core purpose, which is a way of serving others. For example: "I serve others by showing them the beauty of nature."Once the seeker has established his wants, put them in order of importance, and decided on his core purpose, which has a religious basis (it is God's purpose for him), he is on his way to becoming an on-purpose person. Throughout the book, the on-purpose persons use the metaphor of tennis - oddly enough.The book has a cultish quality but little substance. It is similar to a typical (but old-fashioned) book on how to organize your life. These books invariably advised the reader to have a goal, prioritize his desires, and so on.I wouldn't waste your time on this.
