感悟

It's not hard and mysterious to be an expert. From the experience of many masters, we can tell that it's vital to practice for a long time. Many grandmasters are very interested in the field in their early age. And of course they put much time into it. With the time they spend on practicing, there are many mind representations formed. And with these mind representations, they can easily do well in the area they choose. And they can get more positive feedbacks, which motivate them to work harder. And the practice they put lead to better performance. Thus, they form a positive feedback loop. So we can use this to arrange our study.
