" To be sure, temperament and genetics explain some of Nicklaus’s tremendous achievement, but as we know both from research and from his own story, it was also through his relationship to his father, Charlie Nicklaus, that he developed a sense of ownership and accountability. When Jack said, “Dad, it’s my game,” that comment came out of their Corner Four relationship, in which his father was his fuel and his support. But his father also respected Jack’s sense of ownership and self-control. Charlie Nicklaus supported him from the days of playing junior golf up until the pros.
