I find that using the Someday/maybe list is a great way to reduce pressure. When listing projects/outcomes, I find that I can quickly decide what items should be on the current projects listing. They tend to be a mixture of (a) things that need to be done in the next one to three weeks, (b) things that will make a loved one or me happy, (c) things that I know I SHOULD be doing.
By parking the rest of them on the someday/maybe list, I know that they will not drift away and be forgotten, and also that I will have a fresh opportunity to think about them again in a week’s time, at which point I may decide to put some of them on the active list.
Also, of course, only the active projects get Net Actions, so my Next Actions lists are not cluttered with actions relating to projects that I am not committed to at the moment.
Dorothy Lehmkuhl and Dolores Cotter wrote a book called "Organizing for the Creative Person”. It deals with the tendency of us right-brain-dominant types to see everything we have to do as one simultaneous and overwhelming blob. We apparently are missing the ability to see our tasks spread out sequentially along a time-line. Without this time-line, out brains keep telling us that everything has to be done right now.
It is of course utterly impossible to get it all done now. I have found that GTD has allowed me to look at individual tasks “vertically” as DA calls it. That is, it forces me to identify the next sequential action. Somehow, this has also allowed me to think in terms of months. “Okay, I’ve got a lot of projects floating around at the moment, but I reckon that in four months time most of them will be finished”.
The someday/maybe list then becomes a holding area for those tasks that I will not get to this month, but probably will next month or the month after.
