Tennis is a game, and through the game of tennis, everything a person needs to learn about their self can be realized. The game teaches the person. On a personal journey, one’s view of the game and who one is changes over time.
A positive acceptance of where one is at any time on one’s journey is a very helpful tool, although, an experience of dissatisfaction with present circumstances is a common thing to go through. Try to let go of worry about the past and the future. As Jim would say, “You can only play the shot that’s in front of you.”
