Aikido journal recently reprinted one of my articles on the subject of expertise - how the best in the world go about getting better. This got me to thinking on the subject again. Here is another way of thinking about the same idea.
Suppose you put enough effort into practicing kotegaeshi to feel a noticable difference. You have only improved kotegaeshi and you are only able to feel that improvement when kotegaeshi happens.
But if you put the same effort into something more general, like the efficiency of a single step, then that gain is magnified by the number of times you take a step. You are able to feel noticably larger gains in performance when you work on smaller, more general skills instead of more complex and specific skills. Experts spend their time polishing things that affect much of what they do. Experts rarely obsess over singularities.
