This document is the introduction to a book about leadership development for managers. It begins with an overview of the book's contents and structure. The book is presented in a conversational tone and organized into three parts: Part I provides a leadership conversation; Part II contains a story illustrating leadership lessons; Part III focuses on practical application. The introduction establishes that most managers receive little to no formal leadership training, and are unprepared when they take on management roles. It argues leadership is a skill that must be learned, just like any other profession. The book aims to fill this gap and provide useful guidance for developing leadership abilities.
