Mark Messier is one of the most accomplished athletes in the history of professional sports. He was a fierce competitor with a well-earned reputation as a winner. But few people know his real story, not only of the astonishing journey he took to making NHL history, but of the deep understanding of leadership and respect for the power of teamwork he gained. Messier tells of his early years with his tight-knit family, learning especially from his father, Doug—a hockey player, coach, and teacher. He describes what it was like entering the NHL as a teenager with a wild side, and growing close with teammates Wayne Gretzky, Kevin Lowe, Paul Coffey, Glenn Anderson, and others during their high-flying dynasty years with the Edmonton Oilers. He chronicles summers spent looking for inspiration and renewed energy on trips to exotic destinations around the world. And he recounts the highs, lows, and hard work that brought the New York Rangers to the ultimate moment for a hockey club: lifting the Stanley Cup. Throughout, Messier shares insights about success, winning cultures, and how leaders can help teams overcome challenges. Told with heart and sincerity, “is about much more than just hockey. It has lessons anyone can use—be it in sports, business, or life” (Jack Nicklaus, PGA Major Championship winner and author of ).
