While this book certainly does aim high, it only deals with the idea of leadership in a perfect situation or "bubble" if you will. I have to admit I didn't like the book or the author after reading the first page of the introduction. Secretan makes the assumption that we all live in fear and that there is a shortage of people to inspire us (apparently he is here to fill the void). Perhaps I am a minority, but I do not live in fear and can think of many inspirational people, both in the past and present.
As for the rest of the book, he explains leadership in a very new age and ignorant way. Secretan's basic premise is that we all should love each other and that we should all inspire and be inspired ourselves. And that's great, in a world such as that I doubt we would even need leaders as everyone would do what they are supposed to. But in the real world, leaders are confronted with adverse situations such as dealing with subordinates who are unhappy, tired, depressed, going through a divorce, angry, hate you or other teammates, and etc. This book discusses nothing of how to be a leader in difficult situations, or even how to deal with people that you don't love or love you. This is where the book falls down in my opinion. The true test of leadership comes when times are hard, not when everything is hunky-dory. Further, I think Mr. Secretan is a little arrogant in his definition of Higher Ground leadership. He acts as if he is somehow reinventing the wheel when it comes to leadership. Any of the topics he mentions that are actually useful (such as leadership from the front/ serving your subordinates) are ideas that have been around much longer than this book or Secretan himself.
Aside from Inspires lack of useful leadership information, it also has an interesting take on competition. Secretan seems to think competition is bad, and is does nothing more than feed ones ego. He makes such statements as saying a "call to arms" never inspires and "what's wrong with being number two". Again, perhaps I am the minority but I work with small businesses every day. I can tell you that those who don't actively compete often fail.
In the end, Inspire reads more like a new age self help book. Everything from discussing guided meditation, having a divine conversation with God, discovering your destiny and defining your world by how you deal with terrathreats (read environmentalism). If these things are your cup of tea or you hail from a very leftist/pacifist ideology then I guess this book is for you. However, if you are looking for a book that actually deals with how to be a leader in less than utopian situations then I would advise to look elsewhere.
