Why is the weekly review so hard to start?
I've been piecemealing GTD for the last couple of years (using the recently renamed mGSD), never doing a weekly review. Now I'm trying, but feel really weird about it. It seems too huge to be useful/doable in a reasonable amount of time. And I'm only trying to fully implement this within my work areas, before moving on to personal. Right now, instead of doing the weekly review, I'm posting a message on a forum about how hard it is to do the weekly review.
More concretely, do I give myself a deadline and just stop after X hours? It seems like I could spend a whole week putting down everything that needs to get done.
Why do you want to do it?
If it is just a resistance feeling that you don't want to do it, (and not that there are rather more urgent things), then may be a change of focus will help. Ask yourself: Why do you want to do the review? What is so bad about not having it done for so long? What will you have achieved after completing it? Try to be concrete and detailed in answering.
Of course, this is in addition to all the posts above.
