Welcome to the club. As powerful and effective as the Weekly Review is for stress-free productivity, most people avoid it. I wish I had the magic pill that would seduce everyone into doing it, but, alas, that’s not available yet.
First, let’s be clear that it may not be necessary to do every week. The purpose of a consistent review is to maintain trust in your “external brain”—that its contents are clear, current, and complete so your mind can let go of remembering and reminding (which it doesn’t do very well). Your mental energy is best utilized when available for creative and constructive thinking about your world, not of your world.
