When you want to be a writer, you declare that you want to be one of the stars in the sky.
The sky already has trillions of stars. There is no reason for there to be anymore. People look at those trillions of light points and cannot comprehend them. The chances that any person will even focus on one, let alone yours, for even a second, are infinitesimal.
But on the chance that you are that one someone notices, the one that someone makes a wish upon, there is no better feeling in the world. And for that moment you are the only star in the sky.
