Awareness of your self-worth is not a contradiction to the obligation to be humble.

Only a fool is unaware of his positive accomplishments and abilities, and this is not humility. Humility is the internalization 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 feels that what he has is a gift, the greater his humility.
