Golf requires a mental toughness to be great. I see it in my friends who are way better than me. They have the ability to hit a horrible shot and completely forget it and just focus on the next shot as if nothing happened. I cannot do that as hard as I try. That’s why they are single handicappers and I am not.
Meltdowns teach you something important. It teaches you that you are not infallible and that you can fail spectacularly and get up the next day and continue to be the best player in the game. That leads to the mental toughness that is required to play the game of golf at the highest level.
