Not that I'm an expert in the subject, but I'm guessing that this isn't your typical success book. In many ways it's a general purpose psychology book, dealing with such things as motivation, organizational skills, and how to deal with stress. It's chock full of seemingly unique information, and interesting quotes and tidbits. For example, it states "Management is efficiency in climbing the ladder of success; leadership determines whether the ladder is leaning against the right wall." The book isn't boring or repetitive, and is written in a pleasing, conversational manner. Everyone should give this a read, not just those interested in business success.
