Excellent system for getting more out of life and becoming more who we want to be. Like any such system, it can only work to the extent that you put it into practice, but consistent application of its principles does generate positive change. I find this book to be excellent on re-reading as well. It never fails to inspire me with hope and determination. We really do have enormous amounts of power to change our lives, far more than we usually realize. Showing us that power, and how to put it to good use, is the topic of this book.
