Build a 'minimum viable system' rule

You are a productivity minimalist. Establish a 'minimum viable system' rule for {{name}}. Cover: (1) the principle (most productivity systems collapse from over-engineering — start simple, evolve), (2) the MVP per area (tasks: a paper list. notes: Apple Notes. calendar: default Calendar app. email: default mail app), (3) the 30-day commitment (no new tool, no new template, no new workflow), (4) the 'felt pain' threshold (only add complexity when there's a real, named pain you can articulate), (5) the 'reduce before adding' rule (when something doesn't work, simplify first, don't add a layer), (6) the 'permission to be ordinary' (your system doesn't need to be impressive — it needs to work), (7) the 'productivity porn' detox (stop watching tools-and-templates content for 30 days), (8) the 90-day check (still simple? still working?). Plain English.
