As a fellow table tennis player and piano player, I have noticed some interesting spiritual similarities between the two arts. I’m pretty sure they are also common to other sports anyway.
Always think ahead: the next stroke, the next note
In table tennis, one should not think about scoring a point with the current stroke, but rather be prepared for the next. What ball will I get back given my current playing? What do I expect? How am I going to handle it? If we do not think ahead, we will always fall short when the ball comes back, we will not be prepared. In a similar fashion, when playing an instrument, it is vital to know what the next note will be, what the next musical phrase will be. Giving meaning to a speech is impossible if we do not know how it goes on beyond the very current moment.
Mistakes do not matter. If you make them matter, you lose
It is a common phenomenon to make a mistake followed by more mistakes, mostly in the attempt of correcting that mistake/with the case of overthinking the mistake that has already happened. It does happen to make the wrong choice when playing table tennis, or to not get our best stroke, as much as getting a note wrong. This is not a problem as long as we are able to go on and forget that single mistake. Instead, if we focus on that, we end up stressing it and it becomes much heavier.
