I would echo what +Denise Hurd
mentioned about setting an appointment for your weekly review. Get it on the calendar and try to keep that time as "sacred" as possible. In my case, I have to produce a report once a week on the same day, so I schedule my review for just before that (since info from the review will go in that report).
Even if you don't have to produce a report for someone else, maybe you could do one to yourself. Draft a memo to yourself that summarizes the results of your weekly review. For my own report, I like to look for accomplishments and next actions to report on. By actually producing something from the review, that may help guide your efforts and help keep you focused.
