Externalize cognitive blockers immediately in the form 'I

Why This Is a Principle

This is a PRINCIPLE because it derives actionable guidance from three axioms: Open-Loop Cognitive Cost (Zeigarnik) (unrealized commitments consume working memory), Verbal labeling of internal states activates prefrontal (labeling internal states activates regulatory circuits), and Externalization Exposes Hidden Structure (externalization exposes gaps). It's not an axiom itself—it's prescriptive guidance that follows from how cognition works. It's general enough to apply across any blocking situation while being concrete enough to specify the exact form ('I cannot X because Y').
