Who are you?

I have been reading this book called, He did deliver me from bondage. It is about using the atonement in our lives and learning how to give all our weaknesses and sorrows to our Savior since He has already paid for them. I was reading yesterday and there was a quote in there that just stuck out to me. It said, "what you choose when you can do anything you want is what proves your character.' I couldn't help think about this all day. Really who are you when no one else is watching, and you can choose to do ANYTHING? It is a good reminder for me of who I want to be.
