getting organised

So I am half way through the Getting Things Done book.  And I have got to the point where it suggests I take 2 whole days to create the system in my home and clear the backlog.  Normally I would skip this and go straight to using a few of the suggestions or tricks on a more ad hoc basis.  But this is something I need to learn and implement.  So I am thinking I am going to have to go the whole hog on it.  WOAH.
