I have taken seriously the concept of getting everything out of my head.
I have a small notepad on my desk, a David Allen Notetaker Wallet (excellent) and an audio recorder in the car. I'm also very busy and a lot of my stuff I can't deal with as it crops up. I do OK with processing email by using the Outlook GTD Add-in (also excellent) but my projects are building into very long lists too.
But my in-tray! It fills up sometimes inches deep and I'm not good at reviewing on a weekly basis. When I finally get to work on "getting in to empty" it's more like doing an archaeological dig, with the items near the bottom being of nearly historical significance.
I wonder if I just collect too many thoughts, ideas, notes and deferred plans. Perhaps I should be more sparing with what I collect.
Does anyone have any suggestions?
