I am SUCH. A. Hypocrite

What is the word for a person who reads this inspirational story with barely uncontainable excitement, joins up for the group, begins plotting new ways to recycle and reuse, and then, with nary a blink of an eye (and there's no pun intended there), ends up going here to purchase the favorite mascara she wants because she is running low. Yeah, I hear you. I have a long way to go.
