To Self 2, a picture is worth a thousand words. It learns by watching the actions of others, as well as by performing actions itself. Almost all tennis players have experienced playing over their heads after watching championship tennis on television. The benefits to your game come not from analyzing the strokes of top players, but from concentrating without thinking and simply letting yourself absorb the images before you. Then, the next time you play, you may find that certain important intangibles such as timing, anticipation and sense of confidence are greatly improved, all without conscious effort or control.
