What you dislike in your superiors, avoid doing to your inferiors. What you dislike in your inferiors, avoid doing when working for your superiors. What you hate in those who are in front of you, do not do to those behind you.
The superior man honors his virtuous nature, and maintains constant inquiry and study, seeking to carry it out to its breadth and greatness, so as to omit none of the more exquisite and minute points which it embraces, and to raise it to its greatest height and brilliancy.
The way of the superior person is threefold; virtuous, they are free from anxieties; wise they are free from perplexities; and bold they are free from fear.
To study and constantly, is this not a pleasure? To have friends come from far away places, is this not a joy? If people do not recognize your worth, but this does not worry you, are you not a true gentleman?
Listen widely to remove your doubts and be careful when speaking about the rest and your mistakes will be few. See much and get rid of what is dangerous and be careful in acting on the rest and your causes for regret will be few. Speaking without fault, acting without causing regret: 'upgrading' consists in this.
