practice make perfect! so just keep practicing I even do that.
Yes practice, practice, and practice-----------
Watch videos and read articles it will help you a lot.
Also read this I found it on tennis.com:
Enough practice; I think I'd like to play a match. What's better preparation, lessons or joining a league?
Ideally, you need to do both. No matter how many lessons you take, and no matter how smooth and stylish your strokes become, you must practice using those strokes under pressure. Tennis can be an intense, emotionally taxing game. What works in practice might not work as well when you're facing a match point. League play is a great way to improve your skills under pressure. You also should read some of TENNIS magazine's Mind Game columns, which give advice on all manner of mental struggles the game entails.

Virtua Tennis is waayyyy better if you have Wii Play Control. If not, get EA's Grand Slam Depends who you like better really: SEGA or EA!
Tennis is better than Golf becuase you get a better workout. Also, it gives you more strength on your arms then golf.
Vitua Tennis is heaps better because topspin 3 is played in slow motion and Virtua is a fast action packed game.Virtua tennis is more realistic and its got better game modes
In my opinion Ocarina of Time is better, but Mario Tennis Open has more replayability.
That's only a matter of personal interest. Personally I like tennis better, but the answer depends on who you ask.
