Get the old saying in "Algorithm of Life": If a person wants to succeed, he needs to understand his three "radii". In my understanding, there are three circles:

The outermost is a person's circle of attention, also called the cognitive radius: the first is the "cognitive radius", which should be as large as possible. More stuff. For example, you should take more courses of various types. But don’t think that you can do everything within your cognitive radius. For example, just because you have a general understanding of what futures are, does not mean that you can speculate in futures. You'd better stay away from that thing. We also know about gambling and drugs, and we don’t have to try them.

At this time you have to realize the second "radius", which is the radius of ability and influence. Never do anything beyond the radius of your capabilities. Therefore, the capability radius should be as clear as possible. How capable are we of doing certain things ourselves? What are our strengths, what areas do we have certain network resources in, and how deep are our resources? At what level are these resources located? Just information on paper, or some information? Or have we already formed a scene where we can interact with these connections? In the end, it has a certain degree of deep influence and you say it will definitely do it. This is our resource.

However, there is a third radius, and that is the "action radius". The requirements of the action radius and the cognitive radius are exactly the opposite, which is to be as small as possible. What's the meaning? That is, the bigger you want to do, the less work you have to do, and the larger the scale of the system you will ultimately promote. As long as we do smaller and smaller things and become more standardized, our results will become more and more stable. It can also be said that these can achieve a kind of craftsman spirit-doing things with heart, being highly precise and focusing on one thing.

Large systems are the result of a large number of repetitions of simple elements. For example, the world's top large catering groups are basically fast food. Only if the recipes are simple and there are few steps, can the scale be expanded through large-scale copying.
