The reason why a great river can be the king of a hundred valleys is because it is good at staying in the lower position.
Therefore: Wanting to rule the people, you must place yourself in a humble position. Wanting to lead the people, you must place yourself behind.
The wise person is able to dwell above, and not weigh down the people. The wise person is able to stand in front, and not obstruct the people.
Therefore the world is glad to support him and does not tire of it. Because he does not contend, the world is not able to resist him.
(from Tao Te Ching, verse 66, translation by Robert Brookes)
