I wonder sometimes, how I ever win a single point? Seems that only flip works. Also I cant serve, like I have short buffer of memory, so I cant serve more than two different serves on one day, usually simplest possible, if I try something else, it goes too long or into net. Brain stops to work. The more I practice, the less serves I can return.  From people I always play, and who never practice anything. Strange. Amount of balls hit by finger or edge of bat  is bigger and bigger. Also, I almost cant sweat of tt, neither on practice session nor the tournament( I generally sweat a lot, out of tt). People around me change few shirts, and few towels, we practice same shots, but I never bring towel, neither more than one reserve shirt, because one I play in is always dry (I play attacking style),  even worse, I almost always get cold, and got diarrhea after practice session. Seems that I reach working temperature only when I got angry. But then I miss two many balls, especially slow ones. Despite I always had very good perception and hand-eye coordination, somehow, when opponent is on other side of table, brain and muscles stops working. I still think I don't have fear of defeat, because I'm satisfied when I play good and lose match. I'd rather say it's fear of the ball, if something as this is possible.
