I don't usually rate text books, but this is a great one ... Read it cover-to-cover

In terms of theories and getting familiar with different approaches and styles in leadership, the book is really rich, and I also read it as a handbook for the academic course. There are also some questionnaires to test your or your leader in mind's leadership.
But the point is that the book is not so practical, and in today's contemporary world of business, I am not sure if it can help. For me, it was a second look at my previous opinions and knowledge.
With the truth that a lot of leadership books are written by who are at the top levels in the military, it was a change in attitude.

Phenomenal book for those who truly want to be "leaders" in their work spheres, and not just "managers."

Hard to rate a book that's meant to be a more academic overview type of book. Was it the most exciting book in the world to read? No. But did it do for me what I'd hoped--give me a really good overview of a lot of different leadership models? Yes--absolutely. This book helped me think through relationships between different models/theories and what components I may want to explore further. The way the chapters are formatted are very helpful--a description of the theory, strengths and weaknesses, case studies, and quick summaries at the end so I could at least get a feel for a few models that I didn't want to read thoroughly. Very well done.
