One of the paradoxes of the human experience is that we are all both very, very big and very, very small at the same time. Humility is knowing one's proper size. This means that it is not simply an attitude to be cultivated in those who are more self-important than they really are. Humility must also be nurtured in those who -- in believing they are smaller than they really are -- withdraw from life and self-realization. Humility means understanding that you are not incapable of realizing your potential.
