I have experienced this during my ping pong training...
I was trying to perfect my back hand loop shot but couldn't get hold of it..
So my coach told me...
"take a deep breath son, and play the shot for the sake of it's beauty"
(I was a huge admirer of back hand loop in my day)....
It took some practice to clear my head and I finally perfected the shot and God it was such an amazing feeling, not to win the point but to play the shot perfectly....
