That no music in the morning thing makes some sense to me.
I've recently flipped my days around so that I'm doing the shit that takes more thought in the mornings (mostly writing) and the stuff I can auto-pilot (lettering) in the afternoons. Because I need to concentrate on the earlier stuff, I don't listen to any music, but for the rest, it's all music and podcasts. Before, when I was trying to do it the other way around (lettering in the AM and writing in the PM), it was a total disaster. I'd be too burned out to write by the time I was through lettering.
