Humility

All my life, I had an incomplete understanding of "Humility".
I had one interpretation of it in my youth, and sped into adulthood with it.
I was a humble young man because I socialized with anybody I met, regardless of background.
Nothing could stop me from comfortably hanging with people
in places where others would be surprised to see me.

I am older now and I have learned that Humility is more than that.
One aspect of humility I am working on for me is to submit to reason and the good of humanity.
Shed that "You-can't-teach-me-a-darn-thing" attitude.

How do you define humility?
