Here is the thing:

I do not want to be your favorite thing. I want to be one of them, but not your only.
I do not want to always be your last thought before your eyes flutter to a close at night. I'd like to be on your mind, but not always, not always the last thing.
I do not want to be your first hello and your last goodbye. I want to be a part of the conversation.
I do not want to be your passion. I want to be the only one who can pull you away from your greatest passion. I want to be your greatest distraction.
I do not want to be the center of your world. I want to be a continent, an ocean, a landmark. I want to be a part of something bigger.
I do not want to occupy the entirety of your heart. I want to fit into your heart in a way that if I were to leave, you'd feel the gasping loss of me, but you would carry on.

You see, this is the thing:
I do not want to be The Greatest Thing. I want to be Something.
