Only if you let it. A good psr minimizes it.
Agree with this- it is not the situation, it is your mind's reaction to the situation. Successful greats in sports just think about letting their body do what it is trained to do, no matter what the situation. The key is allowing your body to perform by getting your mind out of the way!
In pool, it is a one shot at a time mentality, with the pre shot routine forming the basis for performing the best stroke possible on each shot- nothing more or less going on in your head until each shot is completed. All of this is built upon gaining confidence that you can perform, confidence quiets the mind.
Many will say: " but how do I become confident if I am not allowing myself to perform under pressure". Well, you build on small success and strengthen your mind so that you become a person who believes in themselves and plays " within yourself". You change your overall life mindset to the "glass half full" from the "glass half empty" mentality.
This is how sports can "build character" - those who already approach life in a positive manner have the early edge on those who fear the unknown - this also manifests itself when it comes to pressure performance in sports.
Conquering fears requires one to be brutally honest with themselves and then resolve to incorporate changes in approach to situations- in pool, as mentioned, a good, consistent PSR, will certainly help one on the way to becoming " bullet proof".
