I think my main issue is that fact that i'm so short so when i serve i really jump into the court and end up in no man's land and end up not having enough time to recover. Most times in high school i can get away with it because most of them just either block it back or don't get to it. Then when i play in 4.0 tournaments they can block it easier. and from the motion from my serve (which is pretty big and fast) I have trouble getting back into the groove. The advice given above has helped me realized what i need to work on and i want to thank you all for contributing it is very helpful. Thank you all.
