Confucius

Look at the means which a man employs, consider his motives, observe his pleasures. A man simply cannot conceal himself! ”

The expectations of life depend upon diligence; the mechanic that would perfect his work must first sharpen his tools. ”

A youth, when at home, should be filial and, abroad, respectful to his elders. He should be earnest and truthful. He should overflow in love to all and cultivate the friendship of the good. When he has time and opportunity, after the performance of these things, he should employ them in polite studies. ”

To know what you know and what you do not know, that is true knowledge. ”

Never contract friendship with a man that is not better than thyself. ”

Silence is a true friend who never betrays. ”

The faults of a superior person are like the sun and moon. They have their faults, and everyone sees them; they change and everyone looks up to them. ”

Everything has beauty, but not everyone sees it. ”

Only the wisest and stupidest of men never change. ”

I am not one who was born in the possession of knowledge; I am one who is fond of antiquity, and earnest in seeking it there. ”
