"His nerve, his memory, and I can't remember the third thing"

This quote by Lee Trevino is most likely referring to the 3 crucial components of a successful golf enthusiast. The first is nerve, which is the ability to stay calm and composed under pressure. The 2nd is memory, which is the ability to remember the information of a course and the shots that have been taken. The 3rd thing is likely the ability to make changes on the fly, such as changing the club or the angle of the shot. This is essential due to the fact that it enables a golf enthusiast to adapt to the altering conditions of the course and the altering conditions of their own game. All three of these components are essential for an effective golfer, and Lee Trevino is likely highlighting the significance of these three elements.
