Last time I told you about some online sources for writing prompts and exercises. Besides the internet a large number of trees have given their all so we scribblers can jump-start our creativity. One of the best books I've seen is A Picture Is Worth 1,000 Words. The subtitle reads: "image-driven story prompts and exercises for writers" and the author is Phillip Sexton. The photographs were provided by Tricia Bateman. Over 110 photos are inside its pages just waiting for us to add our immortal words. It has chapters on the different elements of fiction writing: Beginnings, Description, Character, Dialogue, Emotions, and Endings. Chapter 7 is titled "Story Starters" and has 120 pages of exercises that focus on specific ideas about the craft of writing and working with photos. The last chapter has suggestions for using the exercises a second or third time.
So there you are. Enough suggestions to keep you busy for awhile. And who knows, you just might end up with something some editor might be willing to take a chance on.
Gotta go. My first exercise awaits. There's this letter with no return address. What's in it? How is my protagonist going to react to the contents? Why?
