We’d like to thank all the people around the world who’ve contributed to our work, but the list is too long and our memories too short. We’ve had wonderful colleagues and students at Berkeley, Carnegie-Mellon, Harvard, Stanford, University of La Verne, the University of Missouri–Kansas City, the University of Southern California, Vanderbilt, and Yale, and we’re still grateful to all of them. They’ve given us invaluable criticism, challenge, and support over the years.

Ellen Harris took time away from her work at Harvard and Outward Bound to support this project, offer insights and ideas, and generously give us feedback on our manuscript. As always, Lee is grateful to Dave Brown, Phil Mirvis, Barry Oshry, Tim Hall, Bill Kahn, and Todd Jick of the Brookline Circle, now in its fourth decade of searching for joy and meaning in lives devoted to the study of leadership and organizations.

Many of Lee’s colleagues at UMKC’s Bloch School have provided invaluable support and input, including Dave Cornell, Nancy Day, Dave Donnelly, Doranne Hudson, Clancy Martin, Dave Renz, Will Self, Marilyn Taylor, and Sidne Ward. Bruce Kay continues to help Lee stay sane and productive.

Lee offers special thanks to Henry Bloch for his friendship and for endowing the Marion Bloch/Missouri Chair that Lee has been honored to occupy since 1993. Henry created the chair in honor of his wife, Marion, a truly remarkable woman who died too soon in 2013.

Terry continues to receive excellent counsel and advice from colleagues scattered in various places: Devorah Lieberman, Jack Meek, Peggy Redman, Donna Redman, and Julie Wheeler, University of La Verne; Sharon Conley, University of California, Santa Barbara; Kent Petersen, emeritus, University of Wisconsin; Warren Bennis, Gib Hentscke, and Stu Gothald, University of Southern California; Regina Pacheco, University of Phoenix; Patrick Faverty and Eric Prather, SLO’s Friday Afternoon Think Puddle.

Our lives become more ritualized as we age, and we once again wrapped up a manuscript at the Ritz-Carlton in Phoenix. As always, the staff there made us feel more than welcome and exemplified the Ritz-Carlton tradition of superlative service. Thanks to John Beeson, Grant Dipman, Jean Hengst, Sharon Krull, Rosa Melgoza, Marta Ortiz, Jean Wright, and their colleagues.

The couples of the Edna Ranch Vintners Guild—the Pecatores, Hayneses, Andersons, and Donners—link efforts with Terry in exploring the ups, downs, and mysteries of the art and science of winemaking. Two professional winemakers, Romeo “Meo” Zuech of Piedra Creek Winery and Brett Escalera of Consilience and TresAnelli, offer advice that applies to leadership as well as winemaking. Meo reminds us, “Never overmanage your grapes,” and Brett prefaces his answer to every question with “It all depends.”

We’re delighted to be well into the fourth decade of our partnership with Jossey-Bass. We’re grateful to the many friends who have helped us over the years, including Bill Henry, Steve Piersanti, Lynn Luckow, Bill Hicks, Debra Hunter, Cedric Crocker, Byron Schneider, David Brightman, and many others. In recent years, Kathe Sweeney has been a wonderful editor and even better friend, and we’re delighted to be working with her again. Rob Brandt, Kathleen Dolan Davies, Mary Garrett, Michele Jones, Nina Kreiden, and Alina Poniewaz have done vital and much-appreciated work backstage in helping get all the pieces together and keep the process moving forward.

We received many valuable suggestions from a diverse, knowledgeable, and talented team of outside reviewers. We did not succeed in implementing all of their many excellent ideas, and they did not always agree among themselves, but the manuscript benefited in many ways from their input.

Lee’s six children—Edward, Shelley, Lori, Scott, Christopher, and Bradley—and three grandchildren (James, Jazmyne, and Foster) all continue to enrich his life and contribute to his growth. Terry’s daughter, Janie, a chef and TV personality, has a rare talent of almost magically transforming simple ingredients into fine cuisine. Special mention also goes to Terry’s parents, Bob and Dorothy Deal. Both are now deceased, but they lived long enough to be pleasantly surprised that their oft-wayward son could write a book. Terry’s sister, Patsy, and brother, John, have stood by him in past years when it wasn’t clear which direction his life would take.

We say a special thank-you to Chris Argyris, a wonderful and influential colleague and teacher for both of us, who died late in 2013. Chris’s mix of playfulness, intellect, and willingness to confront anyone about anything were unique. He’s irreplaceable, and we’ll miss him.

We again dedicate the book to our wives, who have more than earned all the credit and appreciation that we can give them. Joan Gallos, Lee’s spouse and closest colleague, combines intellectual challenge and critique with support and love. Her contributions (which included a very helpful nudge on the question of the book title) have become so integrated into our own thinking that we are no longer able to thank her for all the ways that we have gained from her wisdom and insights.

Sandy Deal’s psychological training enables her to approach the field of organizations with a distinctive and illuminating slant. Her successful practice produces examples that have helped us make some even stronger connections to the concepts of clinical psychology. She is one of the most gifted diagnosticians in the field, as well as a delightful partner whose love and support over the long run have made all the difference. She is a rare combination of courage and caring, intimacy and independence, responsibility and playfulness.

To Joan and Sandy, thanks again. As the years accumulate, we love you even more.
