Express and Your-Express (each always capitalized)

Express denotes that part of every human being whose job and interest it is to express oneself without reserve, self-consciousness, or self-censorship. 

Your-Express is used to denote your Express (as distinct from anyone else's Express and from the Express that refers to everyone's Express)

Oneself consists of two parts: Express and Selfish.

Usage example: Her Express wanted to break down and cry uncontrollably, but her Emage didn't think that would be dignified and it held her in reserve.

You can personalize Express by hyphenated it with a name, as in Dwight-Express.
