I think I could post two images of my desk "before/after GTD" as an example. I use to use "piles of stuff" as kind-of-next-action-reminders, things i had to read, things I had to mail, things I had to sign, projects I had to complete, my desk was like a little sand castle with towers of papers all around me, waiting to fall on the floor, constantly reminding me that I was not DONE with anything. Now I changed to a new office in a new job (and started GTD at the same time) and its a totally different world. I am not afraid things will slip into the cracks if they are out of sight as they are all in my system (hpda/ical) and voila: nothing on my desk except a little plastic thingy that holds 5 hanging folders for the supporting data for the projects I work on the most that week. I implemented an inbox and a reference material system at home and although the other user of the home office (aka the husband) does not follow that method (sigh), the room is totally different from the pre-GTD euqivalent in our old flat. However, I don't want to turn into a total neat-desk freak and something I read somewhere (maybe on this forum) made me laugh and reminded me of cutting myself some slack (and of doing a weekly review in the middle of the week!) if I start to have pile on my desk again: Eistein was quoted as saying: "if a messy desk means a messy mind, what does an empty desk say about its owner?".
