What is actionable items?

Actionable items is a concept in personal epistemology: The most concrete level of any hierarchy is where actual implementation occurs.

Example: Your goal hierarchy reads: 'Get healthier' > 'Exercise regularly' > 'Build a running habit' > 'Run for 20 minutes at 6:30am Tuesday at the park near my house.' Only the last item — the leaf — tells you what to actually do. The three levels above it are organizing principles. They explain why the leaf matters and where it fits, but none of them can be executed. You cannot 'get healthier' — you can only lace up shoes and start moving.

This concept is part of Phase 14 (Hierarchy and Nesting) in the How to Think curriculum, which builds the epistemic infrastructure for hierarchy and nesting.
