Story Ideas

Feel free to alter these as much as you want. These are just ideas, meant to stimulate your creativity. c:

Short Stories

1: Write about magic items. Not cliche ones like rings and jewels, though. Perhaps a hat, or a dress. Design them, you can even draw pictures of them to help you imagine them better.
Think about what you could have them do. Maybe increased senses, mind control?

2: Write fanfiction! (Those are stories set in the world of a published universe [Harry Potter, Fullmetal Alchemist, etc.]) The world is already created for you, and many writers don't have a problem with it. In fact, the writer of Shades of Gray got her start in Twilight fanfiction.
Also, I know a person that has completed a novel-length fanfiction, and she has published two novels: The Ram and The Rook.

Novels

1: Perhaps you could write about a girl who's different? Maybe in her world, everyone's conforming, and she wants to break apart the fabric of society and expose a threat. She's being hunted down by the police in that world, and she has to try to avoid them and expose the puppet-masters of the threat to humanity...?

2: Write a journal detailing all the events that happened to you every day. Try to be as descriptive as possible. You may exaggerate the funny events and downplay not-so-interesting events, but don't leave anything out.
