(1) Confucius: "The Analects of Confucius" says: Be determined to learn five out of ten, stand at thirty, not be confused at forty, know your destiny at fifty, listen to your ears at sixty, and follow your wishes at seventy, without overstepping your bounds.

Standing at the age of 30 tells us that in the early stage of our career, the core is to find the contribution area of performance, while 40 without confusion clearly shows that the workplace is confused, and our training logic is to summarize the types of confusion, analyze the causes of confusion and solve them.

(2) Mencius:

Therefore, since Heaven wants to drop people, we must first suffer their minds, work their bones and muscles, starve their bodies, empty their bodies and do whatever they want. Therefore, patience has benefited them a lot.

Mencius' words tell us that the cause is not always smooth sailing. The so-called future is bright and the road is tortuous. He also puts forward how to really look at all kinds of difficulties in the cause and how to gain confidence from the inspirational stories of the ancients.

Romance of the Three Kingdoms: "Man proposes, God disposes, and you can't be strong." ?

I have tried my best, and it depends on luck whether I can achieve my goal.
