How can a teacher not have a fixed mind after working for a long time?

In the process of innovation, when actively seeking new ideas, we should consciously put aside the procedures and ways of thinking that have been formed in our minds, that is, the mindset, and eliminate its binding effect on innovation. Let's look at an example.

Toshiba Electric Company of Japan once had a large backlog of electric fans around 1952 and could not sell them. More than 70,000 employees have tried their best to open up sales, but little progress has been made. One day, a shop assistant suggested changing the color of the electric fan to the then chairman, Ishisaka. At that time, all the electric fans in the world were black, and the electric fans produced by Toshiba were no exception. The clerk suggested changing black to light color. This suggestion caught the attention of Chairman Shichang. After research, the company adopted this suggestion. The following summer, Toshiba introduced a batch of light blue electric fans, which were well received by customers. There was also a panic buying in the market, which sold hundreds of thousands in a few months. Since then, in Japan, and even the whole world, electric fans are no longer a unified black face.

This example is very enlightening. Just changed the color and sold a lot of unsalable electric fans in a few months. The idea of changing colors is of great benefit. And put forward, that is, you don't need advanced scientific and technological knowledge, nor do you need rich business experience. "Why didn't tens of thousands of other Toshiba employees think of it?" Nobody asked, "Why are there thousands of electric companies in Japan and other countries? No one thought of it before and no one asked.". This is because electric fans have always been black, but generation after generation imitated and attacked each other, gradually forming a convention and a tradition. It seems that electric fans can only be black. If they are not black, they are not electric fans. Such conventions, conventions and traditions are reflected in people's minds, forming a psychological set and thinking set. The longer time goes by, the stronger this stereotype binds people's innovative thinking, the harder it is to get rid of it, and the more efforts are needed. From the perspective of thinking method, the valuable point of the suggestion made by Toshiba, a small clerk, is that it breaks through the bondage of the mindset that "electric fans can only be painted black".

The key to break through the mindset is to think and look at problems from multiple angles. When thinking about all kinds of troubles, you might as well relax, listen to music and look at nature or other product information, so that your brain can switch to new ideas when you relax.
