In addition to the Weekly and Quarterly Planning Diaries, you may consider it valuable to compile a Daily Planning Diary.
The Daily Planning Diary has the obvious advantage of providing more detail. It can also provide a useful reminder system and give a more comprehensive analysis of Plan vs. Actual time in order to determine problems of effective time management and their cause. Below you can find a printable copy of the form.
The form provides a "Plan" for the day's time with a corresponding "Actual" and an associated column for diagnosing the reasons why the Actual differed from the Plan. The form also provides for a listing of specific things which need to be done.
