The wise project manager stays with the single principle and understands the team process. He keeps things simple and clear for the team and so the work of the team progresses smoothly.
Lao Tsu tells us:
All men will come to him who keeps the one,
For there lie rest and happiness and peace.
Passersby may stop for music and good food,
But a description of the Tao
Seems without substance or flavour.
It cannot be seen, it cannot be heard,
And yet it cannot be exhausted.
