I have caught myself recently that I produce bad feelings, tears or even anger in my kid while he is playing against me or other kids or training.
I was often saying: hit it earlier, not like that, now you are slow,late, or similar and I got reaction from him. Then I said to myself: What a hell am I doing? From super calm kid I was making my kid nervous and distracted? For what?
Then I stopped. I have made peace with him. I told him that I will not say him anything. Not good or bad.
I told him: Enjoy a sound when ball hits a racket properly, and when that is not happen, next ball will for sure so keep trying.
More he keeps trying, more he will achieve.It`s up to him.
