How a book on the brain boosts leadership

Dr. James Brown writes a review of the book Brain Rules. Why does Dr. Brown think this book will help leaders?

I believe personal productivity and performance as a project manager are directly correlated. Just like we have to lead a project team, we have to lead ourselves to a higher level of a productivity and effectiveness. In all of the leadership classes I teach, emphasis is placed on knowing yourself. When you know yourself it provides you the ability to adapt to weaknesses and leverage your strengths (increase your personal productivity and effectiveness).
