" Wisdom is the warrior’s greatest weapon. When you have wisdom, you are never unarmed, you are never defenseless, and you are never powerless. You need skill to know how to shoot an arrow straight, but only wisdom can teach you how to never need to shoot it. Wisdom is not the result of having learned enough; it comes when you know there is never enough learning. "

― Erwin Raphael McManus , The Way of the Warrior: An Ancient Path to Inner Peace
