In my experience humility is the main thing that makes it hard to teach people. "Why is it important that I learn this, I'm not going to change the world? I just want to learn what I need to know to get by.", thought patterns along those lines is so common everywhere, at work, at school etc. People who think they matter are so much easier to teach, and those who go even further and want to change the world often don't need teaching since they learn it on their own.

I don't believe that attitude is humility. To my understanding, humility requires an accurate assessment of one's own capabilities, but not an over exaggeration.
