Query: Motivation, Emotions, and Leadership

A very disappointing book. While the title and concept of the text are quite promising, the content is sadly lacking. The Authors show an almost unbelievable lack of both understanding and knowledge in the areas of motivation, emotion and leadership. The research on which the books concepts are based also seems dubious at best. All in all,. this book is of little interest either academically or professionally.
