A truly excellent story is built around the character. The character, being who they are, comes to their end which is both inevitable and a complete surprise.
But what if your character is still learning who they are? Then, that is their journey. And who they become and their surprisingly inevitable end is the whole story.
I’m thinking in circles. Who do I want to be? Where do I want to end up? How do I align these two desires with where I am now? How do I begin?
