Voice Inside Your Head

"Who is that voice inside your head?"
You know the one you talk to when you are excited about something. Or when someone you love is sick and you need to ask "why is this happening?" Or when you accomplish something that you are proud of. We all do it, even if we don't consciously realize we're doing it, we tell the stories of our lives to this someone.
We want to hear those stories, the ones you tell inside your head, those genuine stories, the ones that not only change your life, but will likely change others lives too.
So back to the question
"Who is that voice inside your head?"
