Well, I want to start by saying that the following are only opinions, but each writer should also ask these questions:
Where is the breaking point, what should differentiate my stories from the rest?
How do I want to approach my stories?
What do I hope the reader thinks of them?
1. This has to do with style.
It is not presumption , because if the first band I played in had specifically something from Dokken, Running Wild and Accept, that is to say no other, and my comics had great influence from Gímenez, and I approached those projects with that aplomb, then why would I have to propose less when it comes to writing? You never have to be afraid of dreaming big, and if someone criticizes you that you are arrogant or something like that, well, so then screw him.
You must be the first to speak clearly to yourself, it is an act of sincerity, but being a self-declaration of intentions also creates a mental box, the brain knows what it has to do from then on, it does not say: "I'm going to write something to see what comes out "as if it were a walk in the country, it will be clear to him that, for example, those who read your stories will know that not even the cat is usually left alive.
Unless you assume that Hemingway, Capote, or Conrad (and I very maliciously suspect that Conan Doyle and Dickens, too) were the kindest and most sympathetic guys on the planet, I think you will go wrong with being honest, correct, or accommodating to the reader. You don't expect that from those who make horror movies, do you?
2. This has to do with attitude.
You don't need to be a metalhead, but it goes that way. No prisoners. Although, on the other hand, you guarantee delivery and sweat. Passion. If you manage to transmit that to the page, you are no longer thinking about whether the story is YA or the damn thing, nor about the show versus tell or some formula, "oh, it worked for that guy", YOU ARE who is telling a story. Here we are talking about personality, not sales, but approaching the way of writing with the market in mind brings you precisely to the other side of the street. This is why it is so important to ask yourself what kind of writer you want to be. Because it is inevitable that some will find your soups overly salted, but only if you like those soups that you make will there be a chance that someone else will like them. It does not work otherwise.
