Tim, you may come to find that you redefine "training."
Maybe rather than thinking of it in terms of a "break" or "stepping back," allow yourself to include what you're doing and going through as a part of your training.
Aikido is one of those practices that can result in a Tetris effect
. It becomes part of your movement, thinking, and being.
"Stepping back" is simply the active creation of more space.
