CORE DEFINITION

A minimalist six-step method: 1. Before leaving work, list the 6 things to do tomorrow; 2. Rank them by importance; 3. The next day, only do the first one until it's done; 4. Then do the second one; 5. Move unfinished items to the next day; 6. Repeat daily.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Single-task processing: Its power lies in extreme simplicity and forced prioritization. It solves 'choice paralysis' and 'multi-tasking switching costs'.

anchor

Anchor fast decisions

Proposed by efficiency consultant Ivy Lee in 1918. Its mechanism is 'constrained focus': compress daily to-dos to 6 items and force prioritization, eliminating the decision fatigue of 'what to do today', and using strict serialization (finish one before starting the next) to avoid multi-thread switching costs. Limiting the number itself improves the completion rate of important tasks.
