Stop looking at words.

Look at art! Listen to music! Maybe what you need is some song lyrics to get your brain going, or art. Play Sudoku. Go to a coffee shop and watch people. Change your mental or physical environment and see what happens.

Prompt lists

Don’t limit yourself to whatever event you’re writing for! If it’s for a fandom ship week, hit up a themed month prompt list (such as Fluffuary, AUgust, or Whumptober). If you’re trying to think of ideas for a zine pitch, trawl prompt lists from fandom or creative writing websites. Mash the TVTropes random trope button until something clicks.

Tarot spreads

Even if you don’t read tarot on your own, you can find websites where you can do tarot readings. Treat it as a story prompt generator: pick three cards, one that is your protagonist, one that is their goal, one that is their obstacle. Look up the meanings. Go wild! You can use the cards for protagonists, antagonists, story arcs…

Lists

Not prompt lists - but every idea you can think of adjacent to a prompt. Tropes, colors, sayings, characters, types (e.g. species of apple, types of wildflowers, names of cocktails)...

An alphabetical list with an idea for each letter of the alphabet.

A list of 20 ideas, as close or as absolutely wild as you want.

A timed list (write ideas for 5/10/15 minutes). The first chunk may be easy, the last few minutes impossibly hard, but right in the middle where your mind is starting to stretch? That may be perfect.

Once you have a list of any flavor, start looking for patterns: that’s a sign your brain is interested in SOMETHING. What ideas/symbols keep showing up?

Look for unexpected intersections

Ideas or prompts may have unexpected links. Randomize your list! Consider resonances between different prompts; they may seem different in a different order. Pick a not obvious combination of two prompts and follow it to the end - what if you put together “pirate” and “arranged marriage”? Use a wheel spinning picker and see what two things the computer matches up.

You can also take a pair of commonly-associated opposites, pick out their most common stereotypical traits. Now swap them. 

Play with other media

Take characters from one piece of media, the setting from a second (hey look, a fusion/AU!). What resonates between them? Grab a non-fiction book about a topic you’re interested in and read that. Ideas might percolate from a number of unrelated sources into one Super Cool Idea.

Change the setting

Turn a sci-fi show into a fantasy setting, or vice-versa. Add monsters. Add gods; add gods with reality-bending dice; add gods with reality-bending dice who are malicious. Flip your characters' genders. Remove the concept of gender entirely. Send your characters to the dimension next door, where only one thing has changed. Or many things. Or everything. Take the characters out of the plot of your fandom, or replace them with side characters; what changes?

Change your mind

Take the prompt at face value. Or, treat it sarcastically. Subvert the trope - or don't subvert the trope. Write the thing you've always wanted to see, even if you think it won't work. Turn everything about the prompt on its head and look underneath for spare ideas. Come at it from every angle you can think of.

Other people

Talk to people about the prompt. Read Reddit or Tumblr conversations, even ones only vaguely associated with the prompt. Let your mind go in new and interesting directions. 

Cool words

Have you run across an awesome word you wish you could use in a story, or a turn of phrase? Write a story around that. Or if you have a list of cool words you keep anyway, flip back to it, see if there are any that might come together in a story.

Titles

If you have a title you've always wanted to use, let the title inspire the fic instead of the other way around. 

First Sentences

Just start writing first sentences, whatever ones come to mind. Don’t be precious about them; the goal isn’t perfect sentences, the goal is something to get your brain moving. Don’t worry about continuing the story yet! Try and get a bunch down without writing any more of the story. If one speaks to you and demands to be written, go back to it after you’ve got your list down.

Deconstruct a story you love and then rebuild it!

Retell a favorite story (or a hated story you thought you could do better). How did they do X? Why did you love (or hate) something so much? Can you do that with some of your ideas? Take out the main character and their sidekick; how does the story read with just the secondary characters? What if you add someone new? How would the story look different as a documentary, a chatfic, an epistolary collection?
