I use Life Balance to run GTD, and following this discussion, I separated Someday and Maybe into two separate places. Someday is set to begin appearing on my active NA lists nine months into the future. Until then, these items appear only in the master project list, where I can review them each week w/o clogging the active NA list.
Maybe is set to never appear on the active NA lists. I review this each week, as well, and, as time opens up, I can move an item into Someday, with a nine month lead time.
Following the "clear mind" philosophy, this allows me to enter distant possible projects when they occur to me, and then forget about them. Nine months later, if I haven't already either moved the Someday item into an active place or elimintated it, Life Balance will begin to gently nag me about the item.
