I'm sorry I got distracted before finishing. Noodling, for me, me means just playing some random scales and/or chords or whatever comes into your head without any thought to structure, composition, or improving skill or learning something new. This is fine for a few mites at a time. It can be stress relieving. But I have gotten into a ruts with this before, and even now I'm in a rut. I need to find something new to learn and practice.
