This Chinese proverb is as simple as it is clever: 越挫越勇 yuè cuò yuè yǒng – The more difficulties you have, the braver you become. As a verb, the Chinese word 挫 cuò means “to chop off” or “to grind”. So it can be translated: The more grind (you suffer), the more courage (you’ll gain).
This may not apply to all circumstances, but often enough it does. Especially in professional life, you may find support in this sentence when things are not going as smoothly as hoped. (Source)
