Every couple hours, or any time the energy shifts, I tap the compass. Three questions, maybe thirty seconds.
Body
Am I tense anywhere? Am I hydrated, hungry, tired?
Emotion
Do I feel open, neutral, or contracted? Am I doing this because I want to, or because I drifted into it?
Energy
Am I giving too much? Do I want to step back, change pace, or redirect?
If anything comes back even slightly off, that's not a failure. That's information. The whole point is catching it while it's small, because small is easy to adjust and big is not.
The physical half
I take breaks before I need them, not after. Change positions, STRETCH, reset.
Ebb and flow, not constant output.
