The wise project manager expects the best of people and they live up to it. People naturally tend to be good and truthful when they are being received in a good and truthful manner.
Lao Tzu tells us:
The sage has no mind of his own.
He is aware of the needs of others.
I am good to people who are good.
I am also good to people who are not good.
Because virtue is a goodness.
I have faith in people who are faithful.
I also have faith in people who are not faithful.
Because virtue is a faithfulness.
The sage is shy and humble; to the world he seems confusing.
Men look to him and listen.
He behaves like a little child.
