He who conquers himself is the mightiest warrior. - Confucius

The superior man does what is proper to the station in which he is; he does not desire to go beyond this. In a position of wealth and honor, he does what is proper to a position of wealth and honor. In a poor and low position, he does what is proper to a poor and low position. Situated among barbarous tribes, he does what is proper to a situation among barbarous tribes. In a position of sorrow and difficulty, he does what is proper to a position of sorrow and difficulty. The superior man can find himself in no situation in which he is not himself. In a high situation, he does not treat with contempt his inferiors. In a low situation, he does not court the favor of his superiors. He rectifies himself, and seeks for nothing from others, so that he has no dissatisfactions. He does not murmur against Heaven, nor grumble against men. Thus it is that the superior man is quiet and calm, waiting for the appointments of Heaven, while the mean man walks in dangerous paths, looking for lucky occurrences.

You can force the people to obey; you cannot force them to understand.

Even when walking in the company of two other men, I am bound to be able to learn from them. The good points of the one I copy, the bad points of the other I correct in myself.
