The Zhuangzi:

When the workman has enough to do, he stops. If he does not stop, he will be wearied.

When he has enough to use, he puts it away. If he does not put it away, he will be harmed.

When there is enough, stopping is fitting; to go on beyond this is confusion.

“If you have never tasted, tasting is what you need: / words cannot impart the flavor of honey.”
