1-3-5 method: what it is and what it means

The 1-3-5 method is a fixed-number structure that sets exactly 1 big item, 3 medium items and 5 small items every day, for a maximum total of 9 items. The number is given and non-negotiable: adding a big item means removing another one. This way the structure stops the list from swelling through a structural constraint, not through personal discipline. Sorting items into big, medium and small needs periodic recalibration based on your own work profile.

A fixed-number structure for the daily to-do list: 1 big item + 3 medium + 5 small = a non-negotiable maximum of 9 items. It stops the list from swelling through a structural constraint, not through personal discipline.
