A critical part of any time management system is the activity of Listing.
In the prior component, Scheduling, I addressed the power of expanding the use of a schedule from a mere Appointment Calendar to a possibly useful planner of each and every kind of activity that places a time demand on a user.
As useful as a schedule is, however, it has its limits.
Any user that tries to schedule too many items into a calendar will ultimately cause their calendar to fail from the weight of too many time demands. At the moment, there is no calendaring system or technology that exists that will not fail from over-scheduling.

Listing involves putting a time demand on a list that is created to pull together items that share some common attribute.
