The document discusses how golf is a mental game that requires focus and mental strength. The best golfers develop "tunnel vision" and focus only on the next shot, letting the rest of the world fade away. They are also able to quickly move on from mistakes by limiting their self-criticism to the 10 yards after an error. Golf also demands mental strength as it is not a short game, and those who can finish all holes despite challenges show determination. Being outside in nature also helps relieve stress and shows how golf benefits the mind.
