A prompt disguised as role-playing…

Go to a thrift shop and purchase an outfit, or choose something out of your closet that’s totally out of character for you. Complete the ensemble with accessories and attitudes that complement what you’re wearing. Now, go hang out in places that would attract your alternate ego, and test out your new duds. Do people treat you differently? Do you treat them differently or feel any different? Now find a quiet place to relax and write about your experience. Apply it to a character in one of your stories. Actually, you could begin the whole exercise with a specific protagonist/antagonist in mind. Just remember to stay in character as much as possible throughout your little expedition.

A prompt disguised as a field trip…

Go somewhere you wouldn’t normally go. Transportation museum? Antique mall? Local baseball game? Find some inspiration for a story or put a character from your WIP into the setting you just visited.
