In recent years, a term has become popular: "involution".
It's just that efforts and sacrifices are not proportional. Every day, we are busy but still can't find a solution. The frog boiled in warm water is gradually worn out.
After humans entered the industrialization stage, the division of labor became increasingly detailed. Take the Internet industry as an example. Every link, from products, business, development, design to promotion, is very meticulous and professional. During the period of rapid development, they drive and promote each other. After the period of rapid development, it is very easy to enter a long-term state of self-repetition and stagnation, consuming each other.
The same is true for individuals. The efforts made in the early years have enabled them to grow rapidly. The work experience accumulated over the following decade or so can be an advantage, but it could also be a risk. Once you enter a state of relying on your past achievements, you should be vigilant, as the trend of internal competition may have already begun.
How can it be solved? It seems that this might be inevitable. The only way is to detect and treat it early. One needs to step out of their comfort zone or enter a completely new field at the right time. This requires courage and comes with great risks. But if one doesn't do so, they will enter a state of self-consumption, and in the end, it might be too late to change.
