Bad Cookie, a fun site that gives fortune cookie fortunes. It makes a great opening line for a story or set the fortune as the character’s destiny and build the story around making the fortune accurate. It both makes writing the story more difficult and easier. More difficult in that the story now has constraints but it also gives you a starting point which helps defeat that “I don’t know what to write” feeling.
You could also compose a haiku based on the fortune, make it a line in a limerick or translate it into the voice of various characters you’re reading or from the media.
