Episode notes
Pick One Task Vessel And Stick To It
- Choose one storage vessel for tasks and stop switching between holders to avoid lost work.
- Define when you'll check each input (e.g., sports app twice weekly, email three times daily) and build rituals to process them.
Resolve Every Open Checkbox Each Day Or Week
- At day/week boundaries, decide: do the task, migrate it, or drop it — never leave unchecked items lingering.
- Sarah uses bullet-journal style migration arrows to move unfinished items to future weeks or cancel them.
Calendar-Linked Tasks Beat Long Infinite Lists
- Tying tasks directly to the calendar reduces activation energy and task-system aversion.
- Sarah and Cal note people avoid bulky task systems; placing weekly tasks on the calendar makes them visible without overwhelming.
