Batch information consumption into scheduled windows rather
Batch information consumption into scheduled windows rather than processing it continuously, because task-switching destroys flow states and imposes recovery costs far exceeding the interruption duration.
Why This Is a Principle
Derives from attention residue (Task-switching generates attention residue that persists), flow requirements (Flow occurs when challenge slightly exceeds current), and task-switching costs (Task switching between different types of cognitive work). The principle prescribes batching as a specific design pattern to minimize switching costs. It's actionable (schedule specific windows), general (applies to email, messages, news), and addresses a distinct operational challenge beyond the axioms themselves.

Urgency is usually noise
Things that feel urgent are rarely the most important — urgency is a noise amplifier.
Attention is a finite resource
You wake each day with a limited reservoir of focused attention — roughly three to four hours of genuine deep work — that depletes with every act of sustained concentration and cannot be refilled by willpower alone.
