Tao Te Ching 9

Better stop short than fill to the brim.
Oversharpen the blade, and the edge will soon blunt.
Amass a store of gold and jade, and no one can protect it.
Claim wealth and titles, and disaster will follow.
Retire when the work is done.
This is the way of heaven.

Being quiet

Brim-fill the bowl,
it'll spill over.
Keep sharpening the blade,
you'll soon blunt it.

Nobody can protect
a house full of gold and jade.

Wealth, status, pride,
are their own ruin.
To do good, work well, and lie low
is the way of the blessing.

9. Retire

Fill a cup to its brim and it is easily spilled;
Temper a sword to its hardest and it is easily broken;
Amass the greatest treasure and it is easily stolen;
Claim credit and honour and you easily fall;
Retire once your purpose is achieved - this is natural.
