Quote by Jack Nicklaus
Success depends almost entirely on how effectively you learn to manage the game's two ultimate adversaries: the course and yourself.
Summary
This quote highlights that success in any endeavor relies heavily on effectively managing two major challenges: the external factors (i.e., the course) and the internal factors (i.e., oneself). It emphasizes that achieving success requires not only mastering and navigating the external obstacles and circumstances (the course), but also controlling and managing one's own thoughts, emotions, and actions. In other words, understanding and effectively managing both external and internal adversaries are crucial elements in attaining success.
