It might sound crazy to certain people, but I got an advice that can work for anything, from finding your location in a large city, to playing a sport or learning about more academic stuff like physics, economics or literature. There are different types of skills which also correspond to different ways of experiencing and understanding stuff. 1-Empirical experience (movements and sensations); 2-Symbolic experience (naming, representing); 3-Concrete experience (categorizing, ordering, grouping); 4-Formal experience (theorizing, drawing logical relationships). As you move from 1 to 4, you add dimensions to your knowledge and your experience. Some people taste a red wine, seeing notes of berries, vanilla or else, being even able to explain the differences in texture between two very similar wines. Most people don't... they couldn't even tell you anything about a bottle, except it's acid and bitter. Just learning to use the words knowledgeable people use to talk about wine changes the way you experience that wine -- which is why I talk about this. Adding depth to your tennis experience, being able to tell more about your forehand than simply saying "I don't know; I go there and I just hit it," does make a difference about how you play that forehand. It makes a difference about how you understand what your body parts are doing -- because you can and do name these movements. It also work regarding tactics and play patterns... if all you see in baseline rallies are big shots, you won't play the same as if your description was more nuanced -- that comes as an answer to a thread about baseliners. Thinking about the game, sitting on a chair does make you a different player.
