All writing is an experiment.
The judge of the success of an experiment is the reader.
The principles of storytelling have existed since the beginning of human kind. Our minds are wired for it, and some people tell well structured stories instinctively. For all of us, the quality of our stories can be improved by studying, practicing, and actively implementing those principles. That’s not to say there isn’t a lot of flexibility, but the greater the outlier the greater the risk of failure. It’s also true that the greater your fan following, the more deviation editors and publishers accept.
I strongly discourage writers from harboring the idea that they don’t need to learn the craft of storytelling, that they’re free to do whatever they want, and if a reader doesn’t like how something is written, it’s the reader’s problem, not the writer’s problem because there are no rules. I say learn the craft, learn the principles, learn the rules, and then you can deviate and know that you are. Then you can experiment.
One analogy I use is photographic composition. There are rules to composing a photograph. Those rules are as old as art itself. Most people with cameras don’t know them. Some people refuse to acknowledge they even exist. But all photographers, painters, and other artists benefit by knowing and following the rules.
