Have you ever felt like you're not the main character of your own life? That feeling that you're not existing for your own, you exist because you have to exist for someone else's story. You're like that extras hired in the movies, either with a small part in enabling the plot or just to fill a scene. 

Everyone is the main lead of their story, of course you are because it's yours. Then why am I the extra in mine? In this story? More importantly, who the heck is the main character?
