5 knowing the destiny: "knowing the destiny" is not resigned to fate and doing nothing, but trying to do something without seeking results. Therefore, "knowing the destiny at fifty" means that after fifty, I know the difficulty of realizing my ideal, so I don't pursue the result when I do things;

Classic source:

The Confucius in The Analects of Confucius said: "I am determined to learn in five out of ten, standing at thirty, not confused at forty, knowing my destiny at fifty, obedient at sixty, and not overstepping my bounds at seventy."

the process of "forty is not confused, fifty knows destiny, sixty is obedient, and seventy is free to do whatever you want" is a process of gradually improving your ideological level with your age. There are reasonable factors in the process of Confucius' moral cultivation. First, he saw that people's moral cultivation can't be completed overnight, and it can't be done suddenly. It takes a long time to study and exercise, and there must be a gradual process. Second, the highest state of morality is the integration of thoughts, words and deeds, and consciously abide by moral norms, rather than reluctantly doing it. These two points are applicable to anyone.
