True power is sitting back and observing everything; true power is restraint. If others' words control you, that means everyone else can control you; breathe and allow things to happen, especially things we can't control or influence. Let some things pass. Metaphorically, choose carefully what foxholes to sit in, and to die in. Use your intuition, reasoning, and logic to bring about optimal integrity.
"The greatest privilege of a human life is to become a midwife to the awakening of the soul in another person."
-- Plato
