Inside and outside the circle

The inner circle refers to the field that you are good at and sure of, and the outer circle refers to the field that you don't know.

The way to avoid mistakes or failures is to do only what you are sure of and leave the unfamiliar things to experts in that field. The so-called specialization is this truth, and so is the social division of labor.

Nevertheless, it does not prevent us from looking at the problem from multiple angles in our thinking, jumping out of the limitations and judging and confirming whether it can be done in many ways.
