Intrigued by the title, I picked up this book and could not put it down until I finish reading the last sentence. This book provides the most valuable philosophical advice you will ever receive about the balance between the assertive energy and the passive energy that rule all aspects of our life. Since we spend most of our wake-up hours at work, the principles outlined in the book become exceptionally beneficial to anyone who is seeking for "spirituality" and "balance" at work. Learn and Apply, (yes Apply), those principles and you will notice the improvement of the quality of your life. The improvement will not be first in the sense of how much more money you will earn, rather how much happier and how much more capable you are becoming. When you reach that point, before you know, you are on the track for significant career advancement and higher earning power. When you bring this newly developed total self-leadership to your life outside of work, you will notice that no matter how many activities you engage yourself in, you will always have the peace, the center and the wisdom with you. This book should be made a required reading for all companies, from top executives to the very junior staff. It can also be a great gift to someone you really love and care about his/her own personal fulfillment.
