Who Am I ?

This is going to take a bit of thought. Am I what possesions I have aquired? Am I what I own, what kind of clothes or watch I wear? Am I the Sum of my education? The sum of life experiences? Or is it possibly what I do? What I say? Whom I help? Do I make the world a better place?

More importantly who do you think I am?

Above all do I know who I am, and do I like what I see every morning when I look in the mirror.
