My largest challenge so far has been attempting to properly format and adhere to the rules of grammar when dealing with dialog. The issue is even worse since my story has been fairly dialog heavy so far (including a fair amount of internal). I've read that dialog should placed within its own paragraph and yet I've seen countless examples of dialog mid-paragraph. Should each line of dialog have its own paragraph, or should a new paragraph be started only when the speaker changes? Should internal dialog follow the same rules of spoken dialog? Currently all the internal dialog is presented without quotes but is italicized. I also have a few instances where spoken / internal dialog is interrupted by others or events. I'm currently signifying an interruption by using dashes. Ex: "I'm talking about something really inter-" some interrupting action. Any help would be greatly appreciated. I can't say for sure but I think (other than research) a large portion of my time is being taken up by wrestling with the dialog presentation.
