Do successful people have to be rich? Is money the measure of success? Can’t being mediocre be considered a success?

I have to admit that today’s society is a materialistic society. The contemporary crowd does not recognize others before others. College graduates change jobs back and forth for money, and government officials also commit corruption for money. Therefore, in the eyes of most people, money means success, and rich people are successful people. The meaning of success has become distorted in the eyes of this generation. In fact, the absolute amount of money is not the only criterion for measuring success. Throughout history, Mao Zedong is definitely a truly successful person. Since Mao Zedong is too far away from us in the later period, we only discuss him in the early period. The young Mao Zedong was not rich. Compared with his classmates at the First Normal University, they were still somewhat poor. He ate vegetarian food and wore old shoes. Today, he is still a poor person. However, he was the one who got full marks and ranked first when he was admitted to the First Normal University. He was undoubtedly a success. A poor person can still be a successful person. This is undoubtedly a joke in the eyes of most people, but I don't think so. Success cannot be measured by a unified standard, money can only be regarded as a standard. For example, we cannot say that a migrant worker earning 20,000 yuan a year or a teacher educating thousands of students is unsuccessful. For them personally, their sense of accomplishment will never be inferior to that of Bill Gates. Success in the true sense should be about surpassing yourself again and again, not the absolute amount of wealth.
