Whenever someone talks about how they need to go outside “the rules”, they are told “you can do that when you are Quentin Tarantino”.
So when do you know?
I have always disregarded something’s that have never helped me tell my stories. I use things like “we” when I have to, I even write things that can’t be filmed.
I have my style and I am comfortable.
But for others starting out. Rather than tell them “they can’t” let’s tell them when they can.
I’ll start “focus on story telling. tell the best and most compelling story possible. everything else is secondary. crap no matter how well formatted is still crap”.
