I am reviewing after 10 days of purchase and no doubt it is awesome book. I think it is a master key of yourself. I am following all those steps which mention in the books and now I feel positive. The best thing is now I wake up early in the morning for running and exercise which I never did for last 25 years. One of my friend recommend me than I google it and than purchase it. One more thing which I want to share that this is the first book that I ever purchase for reading apart from studies.
