I believe practice will make anything better. I like to hit a tenis ball to the wall. Initialy, I cannot hit well. But after repeat so many times, I find a rhitme of the ball, so I can hit well. That ability apparently influence in my performance in Tennis. I play tennis better than before. And my self-confident increases. Previously, I will nerveous when someone watchs my performance. Now, the nervous is dissappear. Good achievement.
