I am starting at ground zero. I need to purge many years of files, set up reference and action file space, purge many years of old emails, and get my email in-box to zero. Obviously, this is going to take a long time to complete.

In the meantime, what do I do when I get to the Weekly Review and Step 2 is "get in to zero"? Does all the back-log need to be cleared up before you can continue with the weekly review?
