"I can be my own" is the idea that a little girl can be inspired to dream her dream and make it become real, starting with Barbie. The commercial(s) would be as follows: a grown woman rock star is singing to an audience, but her voice is that of a little girl, there is a little girl lost in her own world and playing with a rock star Barbie. Or in an expensive restaurant with a food critic, a woman chef brings him the best mac'n'cheese in the world, there is a little girl eating with chef Barbie.
