One And Only
You're the only you and you are boundless.
Every detail, every nuance, every complicated triumph and shortcoming make up who you are. Even if you had a twin you never met grow up in the same conditions and had the same life experiences, that twin still wouldn't be you. All the ingredients could be the same but unless those ingredients were put together in the right way the product can't be replicated. Even if you gave away the blueprint.
No one can be like you, no one can do what you do like you do it and no one can see or understand your vision like you do. You're the one and only you.
