Nice to know I am not the only person in the world feeling disorganized!  I like the idea of using final dates for task reminders.  I recently put together an excel spreadsheet of EVERY report that I do (in rows).  In the columns I have the days (Mon-Fri) and an "X" in the cell once I complete the report.  Since I have daily and weekly, I have cells shaded for days that the report does not need to be completed.  Something very simple and basic for me.  I also have a folder that I use that has all my templates that I use daily.  So every morning I go to that file, open all the templates and close then one by one as they are completed through the day (and X my checklist).  Working for me for  now!  I am sure I will figure something better!
Good luck! ☺
