Be Fun to play against!
Playing and practicing Tennis with Passion can help your development in several ways.
Even if your skill set is not where you want it, try and get to every ball and show your coach and playing partners you are doing your best and you love the game.
You should be able to get multiple practice partners having such a love for the game.
The more desire you have to get every ball back the physically fitter you will become.
The fitter you become the better you will be able to stay balanced against more challenging opponents.
Get fitter and more balanced, then you can improve your variety and shot selection.
Have fun, play with passion, and your game will develop.
