Expanding Ideas

As I finish my first draft of the Firefall movement, I am trying to self-edit by hearing what James and Bill would say to me. I know that I can dwell on a musical idea/phrase/measure for longer than 2 seconds, and I work at expanding my ideas into paragraphs/whole ideas. What I like about using Sibelius is that it is so easy to insert measures into the middle of the music, and today I added about 15 seconds of music into the middle. I had thought about how I might manipulate my already-formed ideas during breakfast this morning, and that is how I have spent my morning. Now I need to figure out how to bring the firefall to an end.
