You need to find your comfort and focus level by playing a ton and find out what works for you. Some people play intense, some are chill, some are something else. I play best when I'm relaxed but predicting rather than reacting. Which is to say when I'm tight and tense and forcing it, it won't be good. When I'm chill but really focused on where the ball is going rather than where it is, that's when I do best.
