Your muse needs to feel important. Give her time and space every day. For me, I try to write a half hour stream of consciousness when I wake up. The devil is in the details. So is heaven.
Concrete details are the magic that draws listeners into a song.
Details create unique images only you have seen. When received by listeners, they are transformed again by their own experience. For example, right now sunlight is illuminating crumbs on top of my toaster. I am distracted from writing and think I really need to clean this apartment. Trust your intuition.
