If you spend too much time think about your oppenents psychological state, you’ll just mess up your own. Or worst, you’ll find them too useful and become dependant on them.

The instructor told me that the cure to having the racquet wobble on my shots was to hit the ball in the sweet spot. well, that is a no brainer
A few racquet changes didn’t do me any good and I figured that I’m always going to be off a bit on my contact point, so the only other
solution was to get a strong enough to fight the miss hits. A bit of reasearch brought me to the Gripstik wrist exerciser . No string and
weight stuff so easy to carry around in my bag. After about three weeks of following the guidelines(not much fun), I have noticed a definite
improvement in my gripping strength which translates to a more stable contact with the ball . I’ m able to overcome the torque of missing
the sweet spot much better than before. Racquet speed also seems to be increasing a bit because of the oveball increase in my wrist and arm
strength .
