there's fog inside of me

It's not clear who I am nor who should I be. It's kind of like being on stage, as part of a play, never having read the scrip. All you can do is improvise and go along. In part I'm afraid of trying to lead the way and ruining the finalie, scrooing up the end. The truth is i'm not the only one involved when it comes to my life. Sure i'm the main caracter, I got the lead role, but what I do afects everyone in the story. And if I don't know where to go or what to do or who to be, then how can I do anything else than to sing along with the tune? I may not know much but I do know I'm not selfish enough to spoil the theme song that is playing on and ritming everyone's life!
