When I was 13, I told my friend in tennis: "I'm joining tennis so I can beat you".
After school, I grabbed a racquet my current-coach's "club" of a racquet and played with him. We only played three games and I lost 0-3.
A year later, I beat him to be the #2 player on the team. I quickly developed more than other players due to intense workout and practicing for hours with other coaches and pros. I even won a few singles tournaments too!
