Much like Nan recently, I have had a wobble. Not physically wobbling - I do plenty of that every day. I stopped using my A5 Filofax for a while.

The way I'd been using it had one little hole in my system. I made notes, mixing in ideas, bits of writing, doodles, and tasks, all at random. I just worked forwards through a stack of pages. The idea was to then process those pages, into my GTD system, and archive pages off as they'd been processed.
