well, in my opinion, people are born with a set of skills, differences, passions etc, that are designed to help direct your life and give you an idea of this "purpose". i think knowing what is life, and self, and absolute will help clear one's mind and help them discover what their purpose TRULY is, what it was meant to be, and not what (thru conditioning and other influencing forces) we THINK it is. i agree, to blindly live with drive and focus, but have it not be on anything specific and meaningful, is foolish.
