I was also thinking about humility.

Humility

I define it as the willingness to learn. Not the subjection of my will to another.
I would venture to say that no one ever learned anything without humbling himself. One must humble himself before the facts... before the laws of nature and nature's God as it were. And those whose knowledge may exceed ours.

Unfortunately, before we do our studies, we seldom know who the true masters are.
