Reminds me when I practiced athletics and had my first competition. I couldn’t for my life do anything right… Dropped out of the endurance race, had a false start on the sprint and threw the weight in the wrong direction.
The worst was the high jump. During practice I was doing really well by being able to clear 1.9 meters (6.2 feet) but during the competition I was not even able to clear 1.4 meters (4.6 feet)… performance anxiety is very real!
So this phenomenon has a name! The Yerkes-Dodson Law.

“The law dictates that performance increases with physiological or mental arousal, but only up to a point. When levels of arousal become too high, performance decreases.”
For me it’s the ability to type. Someone starts watching and immediately every other character is a typo.
Or worse, they compliment you…
I’m sorry about your head injury.
Wow … that’s a lot of talent … mine is more of a wisp or thin formless vapour that you’d hardly notice
Been playing guitar for decades and can play fairly well. When someone watches me play I look like I just picked it up yesterday.
