I just discovered this site. It was mentioned one of the mailing lists I am on.
I have been "trying" to use the GTD system for over a year now. I can never seem to make it fly, however. I am overwhelmed with my index cards full of ideas (the initial braindump), and I always seem to have something more urgent to do than to process cards. I just uninstalled the GTD Outlook plug-in because it was just not working for me. I'm going to give Clear Context a whirl, and see how that goes. I also just downloaded the "Instant Boss", so we'll see how that goes.
There are a lot of elements that I don't like with GTD (tickler file, the waiting on, etc.), but I always figured that I would come back to doing them. I think, after fighting with things for the last year, I realize that if it's not immediately in my face, I won't do it. Having an incredibly limited attention span will do that.
So what I've implemented so far is the Zero-Inbox (although there are still things in the @reply folder that I haven't touched), and the Hipster PDA.
I'm really looking forward to this experiment. I had already done the Week 1 assignment, and although the Week 2 was supposed to be completed by yesterday, I'm going to try to do that right now (since I have a year and a half to draw from), and go from there.
Thanks so much for this experiment. Just reading all the posts this morning has gotten me motivated, and I'm looking forward to more of it.
