This. Spacing yourself from emotion to response - in golf and in life - is the key. You have to give yourself a minute to process what you’re feeling before you can execute what you need to do.
The good thing about nerves on the golf course is they make you zone in on the fundamentals. If you can execute the fundamentals, more often than not you can pull off a good enough of a shot despite the nerves.
It’s like - and I am NOT condoning this - when you hear those people who say they’re better drivers when they’re a little drunk. The nerves make you pay attention to what you’re doing even more than maybe you normally would.
