When I met difficulties in junior high school and almost couldn't hold on, I always said this sentence silently:故天将降大任于是人也,必先苦其心志,劳其筋骨,饿其体肤,空乏其身,行拂乱其所为,所以动心忍性,曾益其所不能。The general meaning of this sentence is“Therefore, if God wants to take the heavy responsibility on someone, he must first hone his mind, test his body shape with hunger and fatigue, and disturb his actions that he has already started. The purpose is to touch his heart with the above hardships and hardships, toughen his character, and increase his original ability.”Sometimes it really helps me a lot.
