The book is divided into two main areas: rational and emotional. I believe that a good manager must first of all master the rational part, but to become an excellent and complete manager, he or she cannot forget the emotional part of the job. Blending the rational and emotional parts will be a recipe for success and fulfillment. The book is a practical guide with intent to offer pragmatic tools and frameworks to new managers. It is the book I wished to have when I started my journey as a manager with business responsibilities. I wrote it based on my real life management experience. I took notes for about four years of the lessons I learned during my first field assignment. I struggled, but finally I have been successful. I wished during my beginnings to have a mentor to coach me and help me to speed up my learning curve. I wish this book can be the practical guide to help others reducing the stress and worries that inevitably happen when taking on a managerial role for the first time. I also wish to help new managers to deliver better and faster high performances.
