There is no enemy. The foe on the battlefield is merely the manifestation of that which we must overcome. He is doubt, and fear, and despair. Every battle is fought within. Conquer the battlefield that lies inside you, and the enemy disappears like the illusion he is. -Rogal Dorn

The warrior who acts out of honour cannot fail. His duty is honour itself. Even his death - if it is honourable - is a reward and can be no failure, for it has come through duty. Seek honour as you act, therefore, and you will know no fear. - Primarch Roboute Guilliman
