How do I practice attention residue?

The most direct way to practice attention residue is through a focused exercise: The next time you switch tasks, pause for sixty seconds before starting the new one. Write down: (1) where you left off on the previous task, (2) what the next concrete step would be when you return, and (3) any unresolved question that might pull your mind back. This is a ready-to-resume plan. Then start the new task. Notice whether the mental pull toward the old task weakens.

Common pitfall: Knowing about attention residue but treating it as trivia rather than an operating constraint. You nod at the concept, then context-switch twelve times before lunch and wonder why your deep work feels shallow. The failure is not ignorance — it is refusing to change behavior once you understand the mechanism.

This practice connects to Phase 4 (Attention and Focus) — building it as a repeatable habit compounds over time.
