My idol has always been my father. He has a really rough life and has respect from all people who know him. For my entire life, I have never heard my father say bad word about anyone and he always listens to his juniors.
probably the ones that plod along under the radar performing random acts of kindness or the one person who out of the blue stands up for someone weaker. or someone who runs to help a stranger. I guess the people who have no names but impact someones world in a positive way.
