No, this is not another one of those "storytelling is the future" long posts about generic arguments and bland clichés.
It's actually a short post about how short stories won me over. I recently discovered Six Word Stories, a blog where the community suggests stories who are no longer than six words. The results are an amazing product of constraints-based creative solutions.
Jay Conrad Levinson once wrote that your brand concept should be no longer than 7 words. Perhaps he was being generous — six seems to be a quite ok number to tell a story.
If you can't strip a concept to its very essential words, your story will most likely suck.
