Query: First, You should know what you are talking about

I began reading this book with an open mind. I am an HR VP with over 20 years of experience at Fortune 500 organizations. This book tries to be iconoclastic and innovative for line management, however, any good manager should see through its marketing and catchy title. This book is based on the "strengths" concept which has no empirical data other than that done by those on the Gallup payroll.I strongly recommend sticking with more trusted and proven business advice from better publishers and authors with degrees in the field in which they are writing about.
