When I hit a breakthrough in my writing... I remember a couple months ago, I was working on the complex story of my planned seven novel series and there were some plot holes. I got frustrated and decided to work on some of my other projects. While going through the big box of them, I came across this story I had developed for a limited-run primetime show for teenagers and there was a small parallel with a subplot from my novel series. I took it and weaved it into my novel series' story and it filled every major plot hole I had. It even left room for a character "return" in a later book after I kill them in an early one. By the time I had incorporated the primetime show story into my novel series' story, I had written seven pages, front and back, of plot. It was one of those "Oh Wow!" moments.
