The Yins and Yangs of Life

I decided to finally submit something for a contest. (whoo...)
Looked fun, so I thought, "why not?"
As the title suggests, everyone has their yins and yangs, as everyone has their good traits and bad traits.
(Whether or not they're in balance is a different story.)

So, as to represent myself, I'd like it to say that I'm a mix of good and bad, of ups and downs, and of lights and darks.
