In most tournaments, I play around 50-80% of my full potential. When I’m playing 100%, yes, I feel amazing. But there are other factors that hinder me from playing my best. Different playing conditions can hinder my performance – different balls, different lighting, different tables, different floor, slight wind currents, strange playing-style opponents, and thousands of other distractions. Also, my preparation can hinder my performance – uncomfortable bed, lack of sleep, fatigue from travel, damaged equipment, and many other elements.
