" Fear is a drug you need to survive. Without fear, you die quicker; that’s part of basic, that’s what the old guys instill in us when we’re fledglings waiting and eager to fly; fear is your friend, but only in controlled doses, never in such flooding waves that you panic. Panic kills you quicker than bullets. Panic turns you into doomed animals. "
