I'm trying to implement GTD for the first time, I read the book and have started to set up a paper based notebook for my lists of Projects, Next Actions, Waiting For, Someday/Maybe, then I added a Miscellaneous tab.
Des, just one warning: I'd be very leery of having a tab marked Miscellaneous. Why? Well, it's far too vague, and if you're anything like me, it will end up as a de facto Too Hard basket. You'll gradually accumulate a bunch of stuff in there that you don't want to think about, which will poison your system.
