We've all had experience with two dramatically different types of leaders. The first type - Diminishers - drains intelligence, energy, and capability from the people around them and always needs to be the smartest person in the room. On the other side of the spectrum - Multipliers - are leaders who use their intelligence to amplify the smarts and capabilities of the people around them. In analyzing data from more than 150 leaders, Wiseman has identified five disciplines that distinguish Multipliers from Diminishers. These five disciplines are not based on innate talent; indeed, they are skills and practices that everyone can learn to use-even lifelong and recalcitrant Diminishers. Lively, real-world case studies and practical tips and techniques bring to life each of these principles, showing you how to become a Multiplier too, whether you are a new or an experienced manager. This revered classic has been updated with new examples of Multipliers, as well as two new chapters one on accidental Diminishers, and one on how to deal with Diminishers. Just imagine what you could accomplish if you could harness all the energy and intelligence around you. Multipliers will show you how.
