One way or another, we learn early on that it’s not okay to be fail and perform bad. We are always concerned about the quality of our performance so we are always self-conscious. Having a concern about your performance is not a bad thing but sometimes things are out of your reach, no matter how good you do life surprise you with its moves and defeat you in all sets of the game with a big margin. If you accept , “I sucked, but it's Ok.” Then you free yourself from the guilt and the emotions which hold you back and make you stuck.
