Aspiration is nothing

It is "ambition is not high in years".
Aspiration does not depend on age: y ǒ u ì b ù z à i ni á n g à o, which means that as long as young people have ambition, their achievements are limitless, not in their old age. It also means that as long as you have ambition and are old, you can also do something.
Origin: The 23rd chapter of the Ming Dynasty Xu Zhonglin's "The Story of Gods": "The woodcutter laughed and clapped his hands, nodded and sighed to his son's teeth: 'Aspiration is not high in years, and no plan is empty.'"
Explanation: Qiao Zi clapped his hands and laughed incessantly. He nodded to Ziya and sighed: "As long as he has lofty ambitions, even if he is old, he will be fine. A person without lofty ambitions will waste his time even if he lives to a very old age."
Synonym: where there is a will, there is a way.

What do Mencius think are the objective and subjective factors for cultivating talents

Mencius believed that the objective factor of cultivating talents was the tempering of hard environment, and the subjective factor was the torture of ideological struggle. In "Born in Trouble, Die in Peace", Mencius believed that the objective condition for bringing up talents is "to suffer from mental hardship, strain their muscles and bones, starve their skin, empty their body, and act disorderly". The subjective condition for talent cultivation is "people always err, and then can change; trapped in the heart, balance in the worry, and later work; in color, voice, and then metaphor."
Born in Trouble, Died in Comfort is a well reasoned prose with rigorous argumentation and powerful eloquence, which is selected from Mencius, Under the Message. The author first cites the examples of six people who have finally taken on a great task after the tempering of poverty and frustration, proving that hardship can motivate people to make progress, and hardship can promote people to have new achievements. Then, the author further demonstrates the truth that suffering leads to life and happiness leads to death from two different perspectives: the development of a person and the rise and fall of a country.

You move, breathe, breathe, and move in the sky all day. Why are you worried that the sky will collapse?" The man said, "If the sky is gas, the sun, the moon, and the stars will not fall down?" The man who enlightened him said: "The sun, the moon and the stars are also shining things in the air. Even if they fall down, they will not hurt anything."
