The best time to stop a fight is before it starts.
The best vitamin for developing friends is B1.
The best way to destroy an enemy in to make him a friend.
So the principles of warfare are: Do not depend on the enemy not coming, but depend on our readiness against him. Do not depend on the enemy not attacking, but depend on our position that cannot be attacked.
Those are my enemies: they want to overthrow and to construct nothing themselves. They say: "All that is worthless"--and want to create no value themselves.
