I do the standard weekly review on Sunday nights, religiously. In fact, I often start shelving stuff starting Friday evening on because I can count on knocking it out while I review. It's a good checkpoint, not too often to become onerous, but not spaced out far enough that I feel like things are getting out of hand. I go through all the standard stuff, my to-do's, projects, clean out the email, process receipts, and even try to think about whether I'm sticking to my stated goals.

I've tried doing some more high-minded montly and yearly reviews, but other than the general, New Year's resolution kind of recomittment feeling they give you, they seemed too Stephen Covey, touchy-feely to be of much good. As long as I've been adamant about a comprehensive weekly review, I feel good.
