There is a saying we have all heard, "Practice makes perfect." That saying is wrong! The saying means that there is great value in repetition. In order to learn to do something right, you must do it again and again and again until it is second nature. However, what if you practice it wrong again and again and again? All you have done is perfected doing something wrong! The correct way to say it is, "Perfect practice makes perfect." The genius of the Powernet is it forces you to volley with the perfect motion because it does not work unless you do so. Further it combines the correct motion with hundreds of volleys in a short period of time. So it enables you to "perfectly practice." The result? Your volleys will be crisp, clean and automatic. What are you waiting for?
