Book: Coach Wooden and Me: Our 50-Year Friendship On and Off the Court
Coach Wooden and Me is a book by the NBA's all-time leading scorer Kareem Abdul-Jabbar writing about his priceless friendship with the legendary UCLA coach John Wooden. In the first chapter of this book, he mentioned that the coach should focus on making his player a better person, not just a better basketball player.
This reminds me of the book Trillion Dollar Coach about Bill Campbell whose mentoring some of the most well-known entrepreneurs like Steve Jobs, Larry Page, and Eric Schmidt. The book is also talking about how Bill Campbell fostered the personal growth of those business executives as better people.
