The area around the service line requires the most tennis skill to play effectively. In fact, it is often called no man's land, suggesting that you should never be there. While this is not true, because many times attacking or defending you should be there, you should leave that area as soon as possible. It is easier to defend at the baseline and much easier to win at the net, so leave that difficult area when you can. Many league players get to the service line and then spend the rest of the point there. In fact, I see it so often, that I call that area in my lectures "home", as so many players do not attack further once the get to that area and they are happy and contented to finish the point there. Home to me is the net. Where is it to you?
