Discipline is wise.
original text
A gentleman's journey is quiet to cultivate one's morality, and frugal to cultivate one's morality. Not cold, not awake, not quiet, not far away. If you study quietly, you must study. If you don't study, you won't learn widely. If you have no ambition, you can't succeed. There is no energy for promiscuity, and there is no cure for danger and impetuousness. As time goes by, your heart goes away, and you become withered and unable to meet the world. What will happen?

A gentleman with moral cultivation perfects himself with meditation and cultivates noble character with simplicity and economy. Without a clear heart and desire, you can't make your ambition firm; Without stability and tranquility, you can't realize your lofty ideals, and you can't study hard for a long time. To learn real knowledge, we must let the body and mind study and discuss peacefully, and human talents are accumulated from continuous learning. If you don't study hard, you can't grow and develop your talents; If you don't have firm will, you can't succeed in your studies. Indulgence and debauchery, negative neglect can not make the mind cheer up; Hasty adventure and impatience can't cultivate character and make sentiment noble. If we waste year after year, the time of volunteers will eventually grow old like dead leaves. Such people will not be used by society, but will benefit society. They will only be trapped in their poor home sadly, and it will be too late to regret it.
