(heads up before reading i have a form of dyslexia if my grammar or words are off)
I feel like the same advice always circles around when talking about writing good dialoge, you have to use subtext, make each line purposeful and try to create distinct voices. But i feel like every other peace of advice is always brushed over, and never talked about.
Creating characters that sound like a person talking and being a character living are like two completely different things. The first one is just mimicking something and the second one is actually creating something, and like the gap between them is huge but bascilly invisible. I really do think that understanding your characters is just not enough, like yeah that does give you the blueprint but, you also have to REALLY understand people, like you need both, and the thing is that i think its something you cant really do in my opinion but more something you just feel or sense which makes it so hard to learn.
Ive heard the advice of how the more personal it is, the better it is, and I think being told that at face value really undermines how deep that goes. It really is the difference between a script having characters that live for scenes and characters that are LIVING through scenes.
I know some people will just say to write the scenes, then through drafts it comes through, but i personaly think its more complicated then that.
Just some thoughts I was thinking about. Looking for thoughts on it as well.
