This book is amazing. I teach leadership and I have read many, many books on leadership. With the POSSIBLE exception of Maxwell's 21 Irrefutable Laws, I would say that this is the best book I have read on the subject. I found myself drawn into every page of the book, often saying "Wow, that is SO true."
Perhaps I am a bit more eclectic than some others who have posted reviews but I don't see how anyone can minimize the brilliance of this book because some of the lessons learned and stories told occurred in Christian ministry. I am a business professor who teaches leadership in the area of sales management. If I read a great insight on leadership from John Wooden, I don't say, "Well that insight is for the athletic world." If I read insights from Patton or Eisenhower, I don't say, "Well, I guess that was targeted for the military market." If I find insights from Gandhi or Churchill, I don't think, "That doesn't apply to business because they are clearly talking about political leadership." How small does your world have to be if you cannot learn lessons from great leaders regardless of their field? I do like the fact that so much of Ortberg's experience is in business but I also like a lot of the lessons I have learned from her leadership at Willow Creek and other Christian ministries.
She was talking about a Christian ministry when she did an outstanding job discussing the importance of passion. I found that discussion fascinating and I thought of twenty ways it related to sales management. But she also drew from a wealth of business leadership experience to really drive home some points. For example, I think I will always remember the advertising agency that regained its sense of purpose and vision by putting away all of their awards (things they had accomplished in the past) and replacing them with representations of their goals (things they want to accomplish in the future). Then, at another place in the book, she hit me right between the eyes when she said that "Eleven time out of ten, the answer to your most burning leadership issue is to have the conversation." I thought of all the times I have not been the leader I needed to be because I wasn't willing to sit down with someone and have a two-way conversation about some issue or concern. Funny thing is I don't know if the story where this insight came from was in a Christian or a business organization. She never said. She didn't need to because it doesn't matter. Whether you are running a church, a business, a political campaign, a sports team, a hospital, a university, or any other type of organization, if you are too weak to sit down and "have the conversation" with someone you are leading, you are not fit to be a leader.
So I guess if you get the hibbie jibbies at the mere mention of somebody's faith, then indeed, steer clear of this book. After all, it is published by Tyndale Publishing (that should give you a hint that God might be mentioned). On the other hand if you want and absolutely outstanding book of brilliant insights from someone who has been a leader is a wide variety of contexts, then this book is a must read for you.
