1. Thinking your “non winning” game plan is going to suddenly start to work.
2. Attacking with your hands and not with your feet.
3. Being off balanced while hitting your shot.
4. Hitting drop shots from behind the baseline and with the wind.
5. Insisting on playing “how you like” instead of “how they don’t like”.
6. Hitting baseline ground strokes into the net. “Not enough net clearance”.
7. Missing too many first serves, or hitting your 2nd serve in the net.
8. Trying to win the point instead of letting them lose the point first.
9. Not being positive with a “fighters confident attitude”.
10. Not controlling the crosscourt rally from the baseline. The person that controls the crosscourt rally wins the match.
