Thanks for the encouragment ya'll. I'm not giving up, but I just couldn't understand it. All of your explanations make sense. I just have to keep plugging away, take some lessons and get back to kicking booty.
Oh, QuietDaze. I *so* totally know what you're talking about. That jump from 2.5 to 3.0 is a beast. I mean, I considered myself to be All That when I moved up from 2.5, and it was so humbling and frustrating and annoying to suddenly be unable to beat anyone in the Eastern Time Zone.
At 2.5, the players can't possibly make you pay for your mistakes. If you're having an off day, you can just push the ball and wait for them to choke. Or just win through superior fitness. Heck, you can stand there waiting to receive serve at love-40 and be pretty confident a double fault is a'coming your way.
At 3.0, you start to see people who can hit consistently, so you wind up making the first mistake. You see people with directional control. Or big serves. Oh, sure. They have big weaknesses, but by the time you find them the match can be over. Then you run into people who are on the cusp of 3.5, and they can make you look bad in a hurry.
There is only one solution: Get better. Get *a lot* better. Pour your money and energy into getting better. Do at least an hour a week just on your serve. Hit against the wall. Take lessons and practice everything diligently. If your instructor wants to re-build a stroke, have faith that this will pay off. Look on the bright side: At least you are already fast and fit. Imagine how distressing it must be for other players who must work on fitness *and* strokes at the same time.
When I was where you are, I decided I didn't want to spend my whole tennis career as a middle-aged 3.0 bottom feeder, so I started completely re-working *every* stroke beginning in May 2006. My strokes in my second year at 3.0 look *nothing* like they did in my first year at 3.0.
And still, there are plenty of 3.0s who can take me out back and spank me good. But at least I win my fair share of matches, and I don't feel terribly embarrassed when I don't win.
It's not an overnight thing, though. You'll probably need to re-set your expectations and have faith that the work and lessons and money will yield benefits in about one year.
It's worth it, though. It's like coming onto the court with way more tools in your tool bag, which makes the match more interesting.
