Alison McGhee, writing instructor and author of many wonderful novels including Shadow Baby (my favorite), once taught a very effective exercise in a writing class I attended. I've shared it before in these posts, but it continues to be an easy writer's-block-breaking recipe, so I wanted to pass it along again, in case any of you are experiencing March doldrums and need a lift.
My memory of the specifics is a little faint, so I'll give you the basics, and encouragement to let it morph to fit your writing needs.
I do remember there were three lists on the whiteboard: people, ages, and objects.
