I have spent some time reading about thinkers and intellectuals who achieved great heights time and again in their crafts. All of them have one thing in common. They never feel settled, never rested on their laurels. A ground breaking scholar is always modest about success, sliding back to ground zero as soon as he has accomplished his goals. The only way to climb higher to another peak, to achieve another scholarly feat, is to traverse again in the valley of humility. Humility in the face of knowledge.
