I've been GTDing since 2009, and I think I've finally established the habit of doing weekly rewiews. I'm up to 16 weeks in a row, and I plan to keep up with it!
One question I have though-- does anyone here really go through their project support materials each week? If I'm to avoid spending an entire day on my weekly review, all I have time for is a quick check that each project has an action item. Any thoughts?
