When you're writing your first draft, do you ever think, I’ll fix it later? I seem to be generating a lot of these with my current WIP. Here's a partial list:
1) Add in more character-specific details – At the beginning of my novel, my MC has a keen sense of smell, but I’ve been forgetting to mention that as I get involved writing down the story.
2) Build a foundation – When I come up with a great idea partway through the story, I need to go back and make sure it’s set up or at least supported by what happens at the beginning.
3) Make it consistent – Sometimes later ideas change a story situation or event (I’m flexible). I might drop or add a character. Change a name. I need to go back and fix places that will make my reader go, Huh?
4) Names of minor characters – I know it’s weird, but once in a while, when I refer to a minor character from an earlier part of the story, I can’t remember their name and don’t want to stop to check. (Maybe this means I need some kind of character chart?)
5) Enhance the setting – During my first draft, setting is one of those things that’s just there. Later, I’ll go back and help to bring it to life with carefully chosen details.
I’m sure there are lots more. How do I keep track of all the things I need to fix? Two ways. I write them right in the manuscript in bold, caps or some other font that makes them stand out from the rest of the story. Or I write about them in my story-specific journal, with a big heading: Fix This Later.
