Why a label does not determine who you are

I was just talking to a friend and she mentioned that she was trying to figure out who she is or what "label" she could place on herself.  My question was why?  You are made of 1,000,000 of different cells so how can one label describe you?  Think about it.  Your hair, finger nails and even teeth have keratin in them but yet your hair and finger nails are so different but are also a part of you.  You are unique.  You are not generic.  Please allow yourself to be you and be the best you, you can be.  Stop the labeling
