Once you know
Lots of people have been making lists for years but have never found the procedure to be particularly effective. There's rampant skepticism about systems as simple as the one I'm recommending. But most list-makers haven't put the appropriate things on their lists, or have left them incomplete, which has kept the lists themselves from being very functional. Once you know what goes
When I refer to a "list," keep in mind that I mean nothing more than a grouping of items with some similar characteristic. A list could look like one of three things: (1) a file folder with separate paper notes for the items within the category; (2) an actual list on a titled piece of paper (often within a loose-leaf organizer or planner); or (3) an inventory in a software program or on a digital assistant, such as Microsoft Outlook task categories or a category on a hand held PDA.
If you've emptied your in-basket, you'll undoubtedly have created a stack of "Pending" reminders for yourself, representing longer-than-two-minute actions that cannot be delegated to someone else. You'll probably have anywhere from twenty to sixty or seventy or more such items. You'll also have accumulated reminders of things that you've handed off to other people, and perhaps some things that need be placed in your calendar or a "Someday/ Maybe" kind of holder.
You'll want to sort all of this into groupings that make sense to you so you can review them as options for work to do when you have time. You'll also want to decide on the most appropriate way physically to organize those groups, whether as items in folders or on lists, either paper-based or digital.
The Actions That Go on Your Calendar
For the purposes of organization, as I've said, there are two basic kinds of actions: those that must be done on a certain day and/or at a particular time, and those that just need to be done as soon as you can get to them, around your other calendared items. Calendared action items can be either time-specific (e.g., "4:00—5:00 meet with Jim") or day-specific ("Call Rachel Tuesday to see if she got the proposal").
As you were processing your in-basket, you probably came across things that you put right into your calendar as they showed up. You may have realized that the next action on getting a medical checkup, for example, was to call and make the appointment, and so (since the action required two minutes or less) you actually did it when it occurred to you. Writing the appointment into your calendar as you made it would then have been common sense.
The calendar should show only the "hard landscape" around which you do the rest of your actions.
