" 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. He encouraged him, provided a coach for him, and gave him input, discipline, and much more. But he also gave him something huge that all Corner Four relationships give us: autonomy and responsibility. The balance between support and autonomy were there all along. As a psychologist, I can tell you that this balance helped develop the self-control that hit that 1-iron and helped him own the results he got in every other tournament he played. "
