It is important to be who we are, because that's what defines us. Sometimes some people try so hard to be someone that they are not, thinking to themselves, "why can't I be like that?".. "How can I be like that?" and etc, ignoring the fact that we are all different, that God has created us to be unique, to be different. We must learn to accept who we are, to see for ourselves that we are who we are, not we are who they define us to be. We learn to define ourselves, to seek the truth about ourselves and strive to be ourselves.
