We are none of us as important as we think we are.
My father gave me a very good object lesson of that fact when I was a know-it-all, smart-ass teen and thought I was really something. He took me outside, filled a five gallon bucket with water from the garden hose, then told me to make a fist and stick my arm in the water up to the elbow and hold it there. After what seemed like an eternity he told me to pull my arm out of the water and look at the impression that was left in the water. Of course there was none. He then told me that the amount of impression left was exact same amount of any lasting importance any person has.
