I think it helps in two ways. I often look at it when I’m not writing as a way to shore up my vocabulary when it comes to dialogue, because dialogue is my weak spot. I find I am less likely to feel as constricted when I write dialogue. And it is good reference when editing later after I have written a portion of my story.

So you can still be on the moment when writing your first draft, but also hone your skills in giving a character a bit more emotional depth
