To know yet to think that one does not know is best; Not to know yet to think that one knows will lead to difficulty.
Lao Tzu
By accident of fortune a man may rule the world for a time, but by virtue of love he may rule the world forever.
Lao Tzu
When virtue is lost, benevolence appears, when benevolence is lost right conduct appears, when right conduct is lost, expedience appears. Expediency is the mere shadow of right and truth; it is the beginning of disorder.
Lao Tzu
A leader is most effective when people barely know he exists. When his work is done, his aim fulfilled, his troops will feel they did it themselves.
Lao Tzu
To realize that you do not understand is a virtue; Not to realize that you do not understand is a defect.
Lao Tzu
