Reading this book is never boring case, the author has bothered to make it enjoyable with a simple script. So it is accessible to everyone. I am fully satisfied with my purchase and would recommend to anyone curious or those who wish to improve their daily lives. Regarding the chapter on prayer, it is absolutely a place among the other chapters and the author does not advocate it as stated in a previous review. Without going into details, that one is a believer or not it does not matter, no one is obliged to apply this advice. It is helpful from the moment he can help some or some (personal opinion).
