I think this is the main thing about our identity Know thyself, asking "who am I"/"who are you" is important to understand how we have been socially engineered, conditioned and programmed to be who we currently are.But changing is really needed always?Even if you are doing everything good.Changing only needed when you are not being able to go with the society.People never wants to loose his identity.Whenever situation like this comes human try to defend himself.
