As a Humanist - I try to be humble. It's hard sometimes. But I came across this really great video by Diane Kucala about humble leadership.
She says, "Humility is NOT thinking less of yourself; it is thinking of yourself less OFTEN! Humility is one of 14 secrets to great leadership."
This is great advice and it's a great way to think about humility. Think of how much better it would be if leaders - actually - listened. I don't think you can be a good leader if you and trying to be front and center. A good leader pays attentions to the needs of others, to help those others flourish!
