Classify tasks along two independent binary

Why This Is a Principle

This is the core principle of the Eisenhower matrix, derived from Human attentional systems evolved to prioritize signals with (urgency vs importance distinction) and Goals as Perceptual Filters (goals as perceptual filters). It's prescriptive (classify before acting), general (applies to all tasks), and actionable. The two-dimensional classification creates a framework that makes trade-offs explicit.
