I can only tell you what worked for me.

1. I grabbed a stack of blank A4 paper (I like to recycle where I can so used the reverse side of some pages I had printed as drafts for something I had worked on in the past) - I then cut these in half (the stuff I needed to write down was not going to require a full A4 page).

2. I then scheduled myself some 'quiet time' where I could mind dump everything I had on my plate at the moment.

3. The mind dump comprised of me writing a single action/project on each piece of paper until my mind was empty of things I had to do (@projects / @NA's) or maybe wanted to do (@someday/maybe's)

4. Once the mind dumo was done I then set about a 'sorting' process where I determined what was a project (current or someday/maybe) or an action related to a project.

Initially where it was a project the paper went into a 'project' pile, I then culled the 'project' pile into current and someday/maybe.

With the NA's I indicated at the top of the page which project they belonged to (some of my projects were similar so I needed to distinguish the NA's for each project). I then sorted the NA's into @contexts (@home, @web (where I have web/email access), @computer (for stuff that can be done without web access), @calls (for phone calls I need to make), @waiting for (not strictly an NA context but it workes for me to have it in the same place as my NA's))

5. I keep these sheets of paper in a filing system that allows easy access and review them each evening in an effort to get straight in my head what I need to do the next day. I treat this like a mini weekly review.

6. The initial mind dump was just that the 'initial' one, many things turned up in the days following so I made sure that I always have some collection tools available in various parts of the house (A4 paper and a pen) so that I can write down whatever it is I think of). I drop these in my intray for processing either at my daily or weekly review time. I then go through the above process again (and again and again.....)

PS one thing I did learn was to start of lo tech, hence the paper approach. I find it is more portable than my current tech tools allow and it seems to be working.

You might also want to have a look at the David Allen forum also (http://www.davidco.com/forum/) between this forum and that one I have learned heaps about GTD.

Hope this helps to get you started.
