Is there such thing as a "rocker" in us?

Off course their can be a rocker in you. Have you ever been at a stop light and looked over to see the "normal" person in the car next you singing at the top of their lungs or playing air guitar? They are letting their inner rocker out. Anyways, if this is something you like, go for it. You don't have to change everything over night. Start by learning an instrument or going to a concert and go from there.
