I am trying to write a fast-paced, action novel aimed at teens and so I made a basic outline with big plot points and chapter descriptions. As I am writing, I keep coming up with these awesome additions to my story and plots I would like to explore further and I am forced to ask whether or not it will fit within my outline. I know the point I want to get across and my outline encompasses it, but at this point I feel like I am missing out on good opportunities. I could edit my outline, but I am afraid I'll run into my same issue again. Should I just continue to write with a few edits to my outline or just use my start and end points and let the middle run rampant?
