You stand there on your toes waiting and watching for that bright green ball to come across that net. You see it hit fault one. The next comes at you. You step back, drop your shoulder and swing at that ball. You fallow where it hits. The ball does not come back. Today you have won the match. But next you could not.
So swing at the ball and keep it off the ground. Focus on the ball. Focus on your feet. Stay awake. stay safe.
