Your awareness of your self-worth is not a contradiction to the obligation to be humble. Humility is not a lack of awareness of your positive accomplishments and abilities. Only a fool is not aware of what he really is an this is not humility. Humility is the internalized awareness with every fiber of your body that everything, yes everything, you have is not your own. Rather it is a gift from the Almighty who bestowed His kindness on you. The more a person actually feels that what he has is a gift the greater is his humility.
