My recommendation: 8/10
Summary of notes and ideas
Absolut recommendation. As the title implies, the book is indeed about tennis but the author manages to add timeless principles about how to get better in something in particular and about life in general.
As I also listened to the audio book, I have don’t notes available, but I found the following notes on the web.
Reflections on the Mental Side of Tennis
The most common complaint of sportsmen ringing down the corridors of the ages is, “It’s not that I don’t know what to do, it’s that I don’t do what I know!”
I was beginning to learn what all good pros and students of tennis must learn: that images are better than words, showing better than telling, too much instruction worse than none, and that trying often produces negative results. One question perplexed me: What’s wrong with trying? What does it mean to try too hard?
A player in this state knows where he wants the ball to go, but he doesn’t have to “try hard” to send it there. It just seems to happen—and often with more accuracy than he could have hoped for. The player seems to be immersed in a flow of action which requires his energy, yet results in greater power and accuracy. The “hot streak” usually continues until he starts thinking about it and tries to maintain it; as soon as he attempts to exercise control, he loses it.
The next time your opponent is having a hot streak, simply ask him as you switch courts, “Say, George, what are you doing so differently that’s making your forehand so good today?” If he takes the bait—and 95 percent will—and begins to think about how he’s swinging, telling you how he’s really meeting the ball out in front, keeping his wrist firm and following through better, his streak invariably will end. He will lose his timing and fluidity as he tries to repeat what he has just told you he was doing so well.
The backhand can be used to advantage only on a tennis court, but the skill of mastering the art of effortless concentration is invaluable in whatever you set your mind to.
The Discovery of the Two Selves
Now we are ready for the first major postulate of the Inner Game: within each player the kind of relationship that exists between Self 1 and Self 2 is the prime factor in determining one’s ability to translate his knowledge of technique into effective action. In other words, the key to better tennis—or better anything—lies in improving the relationship between the conscious teller, Self 1, and the natural capabilities of Self 2.
Joan was beginning to sense the difference between “trying hard,” the energy of Self 1, and “effort,” the energy used by Self 2, to do the work necessary. During the last set of balls, Self 1 was fully occupied in watching the seams of the ball. As a result, Self 2 was able to do its own thing unimpaired, and it proved to be pretty good at it. Even Self 1 was starting to recognize the talents of 2; she was getting them together.
Getting it together mentally in tennis involves the learning of several internal skills:
learning how to get the clearest possible picture of your desired outcomes; learning how to trust Self 2 to perform at its best and learn from both successes and failures; and learning to see “nonjudgmentally”—that is, to see what is happening rather than merely noticing how well or how badly it is happening.
