This book celebrates 25 years of the Frances Hesselbein Leadership Institute—sharing the best thinking on leadership and management with our partners in the social, public and private sectors—and our lasting partnership with John Wiley & Sons. We deeply appreciate all those who helped bring this work to fruition: Peter F. Drucker, Frances Hesselbein, Bernard Banks, Lauren Maillian Bias, Juana Bordas, Adam Braun, Jim Collins, Theresa Drapkin, Caroline Ghosn, Kelly Goldsmith, Marshall Goldsmith, Justine Elyse Green, Nadira Hira, Philip Kotler, Jim Kouzes, Raghu Krishnamoorthy, Kass Lazerow, Mike Lazerow, Luke Owings, Michael Radparvar, V. Kasturi Rangan, and Judith Rodin. Joan Snyder Kuhl championed the vision for this new edition and infused her passion for young leaders throughout its development. We owe the book's focus and structure to our talented writing and publishing colleague, Peter Economy.

We are especially grateful to each member of the Frances Hesselbein Leadership Institute Board of Governors, who enabled this opportunity to become a reality: Chairman Will Conway, Carla Grantham, Joan Snyder Kuhl, Charlie O'Connor and Keith Schaefer. From the bottom of our hearts, we thank you. Your support and guidance will impact lives around the world for years to come. Former Hesselbein Institute Chairman Chris Fralic helped ignite this idea and has been a continual source of guidance and support.
