I have recently found myself getting bogged down halfway through the first draft of my WIP. The situation is this – I have groups of characters, each with their own unique subplots, and as the story progresses you begin to see how they are related. Everything culminates at their discovery of each other towards the end, since for most of it they don’t know how they are connected. The problem is… neither do I. I know how I want things to unfold – who has conflicts with whom, the scenes in which major altercations take place, etc. I’m just struggling a bit with the “why” of it all and the individual motivations. Up until now it hasn’t bothered me much, but as the characters begin to collide with each other I obviously find myself worrying about it more and more. So how would you approach this? If you were in this boat, would you soldier on and write the first draft the best you can, filling in the plot holes and making changes as necessary during the revision process, or would you take a break from writing the draft and spend your time brainstorming and writing notes/character sketches to try and figure out the “why”s before going any further in the first draft?
