We have talked previously about how important the weekly review is to your GTD system and to helping you get and stay Organized.
Here is a quick and very abbreviated list of some of the things you might want to do at every weekly review. Please remember that getting your IN-BOX to ZERO does not mean you have done everything. It simply means you have captured it in your system and know where to find it.
The other PRO tip here I would share with you is this... work hard to limit your weekly review time to something between 1 and 2 hours. Unless this is your first real review, if the process is taking longer than this you are likely slipping into "DOING" the work rather than just reviewing the work to be done.
