Care and hard work can rejuvenate a country, while leisure can lead to death.

Career is accomplished by hard work, wasteful by play, accomplished by thinking, destroyed by following. (Han Yu)

The edge of a sword comes from sharpening, and the fragrance of plum blossoms comes from the bitter cold.

If a person has no long-term worries, he must have immediate worries.

Therefore, when Heaven is about to assign a great responsibility to a person, he must first prepare his mind and will, strain his muscles and bones, starve his body and skin, deplete his body, and mess up his actions. Therefore, tempting his heart and forbearance has benefited him. Can't.

(Mencius)
