Where do writers get ideas? The answer is varied and often personal to that writer. I have been getting ideas as I drive to work. A car parked on the side of the road. Why? What if? Those questions can trigger a short story.
Sometimes newspaper articles can generate ideas. A comment someone makes can cause a topic to write about appear in a writer’s head.
I am thinking, since I come up with so many good ideas while driving, that I will drive somewhere if writer’s block every “hits” me. There’s not a day that goes by that I don’t think “that would make a good story”, or “I could write a poem about that”, as I notice things while driving down the highway.
