Break my own rule

This sounds a really interesting idea. At least a person who never takes selfie before uses one of his selfie as his profile photo will definitely shock me and make me think of what is going on. Your special case makes this change special. Maybe you can think of what kind of expressions you will use in your selfie and what kind of message you want to send (if any) with your expressions. That may lead to more discussion about your selfie.

This is sounds like a very interesting way to spin this project. To choose to represent yourself in way that defies the rules of how you present yourself on social media seems like a very brave thing to do. Also, the way you're chronicling the consequences of this action is unique and I honestly never considered doing it that way.
