Confused I am

Who am I today? Am I who I was yesterday? Or maybe I am who I will be one day? Will the me of today be different from the me of yesterday And will the me of tomorrow be the same as the me of today? And who is to say that the me of today aren’t the me of tomorrow who is the same the me from yesterday? What is so significantly different between today, tomorrow and yesterday? Who is to say? That Monday isn’t really actually Tuesday? Or that Sunday isn’t really Saturday? Will I ever be who I want to be? Will I ever discover the real me? Or am I Wednesday just because everyone said I am not Friday? What if I want to be Thursday? Who is to say, that a square isn’t actually really round? Damn, what is this poem about? An even better question…..who am I?
