Sustain

Keep your routine stable when life gets busy

A sustainable system includes normal weeks and difficult weeks. Build primary and fallback versions from the start.

Fallback rule

When time is low, shorten duration, keep frequency.

Weekly check block

Easy actions are candidates for long-term habits.

Friction points should be simplified, not ignored.

Adjust only one variable at a time for clarity.

Short day

6-minute movement and simple evening meal.

Normal day

20-minute activity and balanced three-meal structure.

High-load day

Keep minimum baseline and postpone optional extras.
