"Be polite, be humble and be professional, but always carry a plan to kill everyone in the room."
Info & reflection: The military side isn't mine and I don't share it. What I keep is the mental structure underneath: politeness and humility aren't weakness, they live alongside total readiness, a level of focus and determination that never switches off. Obsession, turned to the positive, isn't aggression: it's never stopping being fully present to what you're doing.
