Here's one example of an artist's story to provide you with some idea of what we're looking for:
"Rue de Varenne in Paris, 2000. It was my second year in the city. I had a 7 square meter maid's room and often had insomnia. When sleep would not come, I would grab my Leica and head out and wander the streets aimlessly until I got tired. This picture was taken around 3 or 4 AM. As I looked through the viewfinder to compose the shot, I immediately identified with the man struggling with the heavy bag. I heard the arrow saying to me, "Keep going, young man. Keep going to the end of the road."
