When I first started implementing GTD and recently as an experiment, I tried to do the weekly review impromptu, off the cuff if you will. This is generally not a good idea. You should make a weekly review list because it’s so goshdarn easy to make. I find the best place to put it is in an email to yourself. Often email is at the heart of folks’ weekly reviews and inbox clearings, so it’s a great place to put the list. Just search for “Weekly review” and get rolling.
Here is mine. Yeah, I have some odd non-traditionals on there, but if I gotta remind myself to do them somehow. What does yours look like?
