Hi all. I've been playing seriously for about a year and am a very strong 3.0. I play doubles mostly. I have a good eye for the ball, good reflexes, good athleticism. I've pretty much built my game from ground up by reading, watching and experimenting. I haven't had any coaching at all so far but I do realize the importance of it. I know I can be a much better player and would like to realize my true potential. So, I've set a goal to be a 4.0 (at least be able to play in the 4.0 league) in a year. (I am 31 yrs old, by the way) I need your suggestions and a road map in getting there. Here are some things I've thought of so far. More are welcome. 1. Play in 3.5 league (which I am doing already) 2. Get a coach 3. Practice only serve at least one day of the week. If possible please suggest what exactly I need to work on in order to progress. Thanks in advance.
