The first line/paragraph of your story is the most important, as it brings people in (Or so I’ve heard). So, if I may ask, how would/do you start your story? (any pov)
I don't think this idea makes any sense in novel writing tbh.
Like, the first 10minutes of your media being the most important is a valid rule because it's when you hook the person you're trying to aim your product towards, but like... First line/paragraph? That's more of an elevator pitch kind of thing than something related to novel writing.
It might be useful if you're trying to pass an audition or whatever, but not really something for novel writing.
I mean... Think about it, who is going to read the first line/paragraph of your novel? Well... The people who liked the cover/synopsis/genres/tags of your novel.
As in, the hooking process doesn't come from your first chapter, but from the other parts of your novel. That's what makes a reader decide if they wanna try your story or not.
Once they've already decided to try it, they're gonna try it... At this point, the reader will only drop your story at c1 if it's complete garbage or the complete opposite of what they expected... Otherwise, they'll most likely read c1 until the end and quite possibly a few more chapters before they decide if they wanna drop your story or not.
So uhn... Don't overthink it too much? The first line/paragraph don't mean much in terms of writing novels. It's generally more important to worry about the prologue/first chapter as a whole than it is to worry about the very first words you're writing.
And honestly, for as long as you aren't dropping some info dumps on the first chapters, you'll probably do alright.
