普通人一般在35至40岁才明白社会运行的真相和逻辑，但刚好被钉在生活的十字架上无力挣扎。

上层阶级早在十几二十岁已经通透，没过多的试错成本，认知与智慧更像一种传承，几代人积累下来的结晶，即“家学”。

人生最大的浪费不是金钱的浪费，而是时间的浪费，认知的迟到。这时已没多余的经历和勇气了。

Ordinary people usually understand the truth and logic of the operation of society only at the age of 35 to 40, but they have just been nailed to the cross of life and are unable to struggle.

The upper class in the early teens and twenties have already understood, not too much trial and error costs, cognition and wisdom is more like an inheritance, the crystallisation of the accumulation of several generations, that is, "family learning".

The biggest waste of life is not the waste of money, but the waste of time, cognitive tardiness. At this time there is no extra experience and courage.
