Greetings ninjas

I have spent the last year trying the various ideas\themes that Mr. Allen listed in his book. And with the help of great resources like 43Folders, a lot of those ideas have helped me stay organized, accomplish goals and have reduced my overall stress.

But there is one GTD concept I have struggled with consistently. And that is keeping a regular weekly review. And no matter what kind of system (paper or electronic etc), no matter how efficient that system, without a regular weekly review, the system quickly loses it usefulness. Then I stop trusting the system, my stress rises, and I start figuring out how to make a better system (another problem all of it's own).

It seems pretty obvious to me when I remove myself from the flurry of incoming tasks and information - if I could consistently keep a weekly review, my system would enable me to reach ninja levels of productivity.

Does anyone else struggle with the review? And does anyone have some tips and tricks to help a person stick to doing a weekly review?
