When you let someone else control the entirety of your identity, you are letting them control much more than just your physical being. Everything they do, becomes what you react to, physically and mentally. Attaching yourself to another person in this way opens you to losing the whole of the identity you sought after with them, when they decide to part with you.
You are replaceable… with the foundation, however, being completely superficial. What type of clothes you wear, the people you hang with, even down to the name to which others call you, can be changed and/or replaced. But when you begin to individualize yourself, your actions and emotions become singular, they become yours. The impressions you leave will forever be imprinted as yours and only yours.
Be you, unapologetically. You are growing and maturing and you will reach many points in your life where you will find you are forced to identify with a concept or person. Make sure it is something you truly identify with, or at least something you resonate with. But by all means, avoid doing or saying certain things simply because you feel as though it is what someone else would do or want you to do.
Be you, be you, be you.
Because at the end of the day, nobody can take that away.
