Sucky serve. I need a serve overhaul - or a new way of thinking about the serve. I want it to be a weapon, but it is so damn inconsistent. And when it starts going off in a match, it can wreck the rest of my game.
The things that hurt my game are stamina and patience. I'm sure that if I were healthier, my stamina would be there. And with that stamina, I would be more patient in trying to figure a way to set up my shots. Alas, it's a dog eat dig world since I'm also playing tennis to get healthier! I guess that's the whole point: even if I lose, I win since I'm getting healthier. :)
