Ordinary people often end up in despair after trying hard, and it is too difficult to go further. Without resources, background, or backstage, and without a deep understanding of social structure and operation mode, they often enter the cruel society with the white rabbit thinking and participate in the social division of labor. The only time and energy they have is bought by cheap wages. Survival is already difficult, so how can they have more time to think? Even if they like to think, they can't think of the point, and they complete the cognitive closed loop under the solidified thinking structure.
Most people can't get rid of their original thinking at the age of 40, and they are struggling on the line of food and clothing. When you get older, you can see clearly, and you don't have the time and energy to develop. Development must be done early, don't be greedy for fun. People who understand the way society works in their 20s, sprint hard before the age of 35, have a stable basic base around the age of 40, accumulate rich resources for their children at the age of 50, and pave the way for future generations at the age of 60.
Life is very short, you must learn to observe society, summarize rules, and refine cognition.
