# Deep Work ## Overview Cal Newport's framework (2016): **deep work** = undistracted, cognitively demanding activity that creates hard-to-replicate value; **shallow work** = logistical, responsive, easy-to-replicate work that fills modern calendars. The most valuable knowledge work is disproportionately the product of deep work; shallow work is increasingly automatable. Three foundations: attention research shows 15-25 min recovery cost per interruption; expert performance requires deliberate practice (structurally a form of deep work); the opportunity cost of shallow work is invisible — no one tracks which deep work didn't happen this week. Composes with [`wu-wei`](../wu-wei/SKILL.md) (flow as the felt experience), [`metacognition`](../metacognition/SKILL.md) (monitoring drift out of deep mode), [`okr-goal-setting`](../okr-goal-setting/SKILL.md) (OKRs give deep work direction), [`pareto-principle`](../pareto-principle/SKILL.md) (the 20% producing 80% of value is almost always deep work). ## When to Use - Output depends on hard-to-replicate cognitive work (research, engineering, writing, design, strategy) - Calendar fragmentation prevents the work that actually matters; weeks feel busy but produce nothing - High-stakes project requires extended concentration; career advancement depends on skill development **Not when:** genuinely high-coordination roles where deep work is structurally impossible; already done with deep work and shallow follow-through is now required; sh
