Tennis psychology is far more than the effect of certain shots, made or missed, on the player. One can sum up such things by saying that every kill gives confidence, every error tends to destroy it. These things are obvious. The branch of psychology that is interesting is the reaction on the various players of different courts, different crowds, and other players.
I could go on writing tennis psychology as explained by external conditions for hundreds of pages, but all I want to do is to bring to mind a definite idea of the value of the mind in the game. Stimulate it how you will, a successful tennis player must admit the value of quick mind. Do it by a desire for personal glory, or team success, or by a love of competition in matching your wits against the other man’s, but do it some way.
Do, not think that tennis is merely a physical exercise. It is a mental cocktail of a very high “kick.”
