The wise project manager is content with what he has. If our goals are clear, we can achieve them without fuss.
Lao Tsu tells us:
Knowing others is wisdom;
Knowing the self is enlightenment.
Mastering others requires force;
Mastering the self needs strength.
He who knows he has enough is rich.
Perseverance is a sign of will power.
He who stays where he is endures.
To die but not to perish is to be eternally present.
