Whatever endeavors you engage in, be sure you engage in the right way. Otherwise, your efforts will remain fruitless.
Realize that everything changes: fullness become empty, emptiness full.
The independence of the superior man is not based on rigidity and immobility of character. He always keeps abreast of the time and changes with it. What endures is the unswerving directive, the inner law of his being, which determines all his actions.
If we are in pursuit of game and want to get a shot at a quarry, we must set about it in the right way. A man who persists in stalking game in a place where there is none may wait forever without finding any. Persistence in search is not enough. What is not sought in the right way is not found.
It is the law of heaven to make fullness empty and to make full what is modest; when the sun is at its zenith, it must, according to the law of heaven, turn toward its setting, and at its nadir it rises toward a new dawn. In obedience to the same law, the moon when it is full begins to wane, and when empty of light it waxes again. This heavenly law works itself out in the fates of men also. It is the law of earth to alter the full and to contribute to the modest. High mountains are worn down by the waters, and the valleys are filled up. It is the law of fate to undermine what is full and to prosper the modest. And men also hate fullness and love the modest.
The destinies of men are subject to immutable laws that must fulfil themselves. But man has it in his power to shape his fate, according as his behaviour exposes him to the influence of benevolent or of destructive forces. When a man holds a high position and is nevertheless modest, he shines with the light of wisdom; if he is in a lowly position and is modest, he cannot be passed by. Thus the superior man can carry out his work to the end without boasting of what he has achieved.
