okay I'm writing a screenplay about Vietnam. So i need different dialoge. I get about 3 quarters of the way through until i start thinking my dialge is $hitty. like really bad. So i go back and change it . But know i have deleted a good amount of my screenplay and now am taking forever to decide on a certain line or paragraph. Any advice on how to steady my mind on somthing or how to make up my mind?????\



Also how long should it take to write a 115 page screenplay?????????

First off, it's spelled "dialogue."

You can't think too much when writing a first draft.  It's better to just write it out and get through it, then go back and edit your dialogue and whatnot.  Also, you posted something similar the other day.  I recommend you look through some of the old threads because there's helpful stuff there that may help you out.

And everybody writes at different paces.  It takes me 6 months to write 115 pages.  I takes other people a week.  It just depends on you're writing strategies.  

Hope this helps
