Laozi wrote: "Know contentment and you will not be disgraced. Know when to stop and you will not be in danger. Thus you can endure."
The phrase "知止不殆" (know when to stop, and you will not be in danger) is Laozi's warning against the endless pursuit of more. The businessman who knows when to stop expanding will not overextend. The warrior who knows when to stop fighting will not be destroyed. The lover who knows when to stop pursuing will not lose respect.
知足不辱，知止不殆，可以长久。
知足不辱，知止不殆，可以长久。

Core Wisdom
The one who always wants more is always in danger. The one who knows when to stop is always safe.
This teaching is the Daoist answer to ambition. Laozi does not say "do not achieve" — he says "know when enough is enough." The danger is not in having things, but in the inability to stop acquiring them.
The word 止 (zhǐ, stop) is central to Daoist ethics. It appears throughout the Dao De Jing as the counterbalance to 动 (dòng, movement). The wise person knows both when to act and when to stop. Most people are good at the first and terrible at the second.
