One of my favorite things, is inspired by something tangible...
Do you have a "junk drawer"? Go through it and write your memories of what you find.
your closet...find a piece of clothing you wore that has a memory for you, if you like extra challenge? Personify it and write the memory from the point of view of say...um, your favorite pair of boots?
If you have perfume, choose a scent, and let it speak to you...or a book, or even furniture--a favored coffee cup or tea cup?
Or--and I've done this a few times--look directly over your computer monitor, if there is something hanging on the wall, let it tell you a story.
And if none of this appeals to you--try writing something where nothing is there--an empty bench at a bus stop--or a broken pay phone, the coil dangling...
Tell me a story.
