Well I will go with money.
The definition of Beauty is quite misinterpreted only because people have different opinions on to what they find beautiful....and somehow forget that true beauty lies within and not by appearance.

Money on the other hand is pretty straight forward, I want to survive on this world so I need it, if I want my physical looks to get any better again it is money and if money does not go over the head of a person and he chooses to use his money for good as in helping others then he just achieved true beauty through generosity and kindness.

Heh, I am done getting my mind wander off for the day....that was fun! :P
