The Big 3 Priority Method for Daily Planning on iPhone
How marking three must-dos per day cuts decision fatigue, keeps your timeline focused, and pairs with timeboxing in DayBox.
Why three priorities, not ten
Unlimited priority flags mean nothing is priority. The Big 3 method caps must-dos at three so "important" stays meaningful when Slack and email compete for attention.
It is especially useful on iPhone where screen space rewards clarity over sprawling project views.
How to pick your Big 3 each morning
Choose one outcome tied to a deadline, one that moves a long-term goal, and one that prevents a predictable fire—client deliverable, gym habit, expense report before finance chases you.
If you cannot fit all three on the timeline, shrink scope or move one to tomorrow before the day starts.
