There should be one rule for writing (and living your life): If it works, do it. If it doesn’t, don’t.
Of course, many people have come before us and they’ve learned a few tricks here or there. Like second person is not really the best way to tell most stories. And active scenes are more engaging than passive scenes. And if you use good spelling and grammar then you can get out of the way of the story and let the reader and the story interact.
But, I see so many discussions about how long should a chapter be. (Whatever length works. There’s even one book I read that was one never-ending chapter.) Or, what POV or tense should be used. (Whatever works best for the story you want to tell unless the readers of that particular genre are so stuck in the mud that they won’t accept any POV or tense other than the one they’re used to.) Or any number of other, highly individual choices that should really be up to the author.
Not that other people won’t have opinions. My god do other people have opinions. But do you ask random people on the street what they think of your shoes? (Ask them and they will tell you, because that seems to be the nature of human beings.) No. You wear shoes that work for you and what you want to accomplish.
That’s how I think it should be with writing, too.
