The unschedule

Check out the Dilbert Comic Strip from June 8th. Mega-consultant Dogbert is telling the pointy haired boss to keep a journal of everything he does during the day.
This reminded me of an idea in the book The NOW Habit from Neil Fiore called "the unschedule".

It tells you to write down only previously committed time into your calendar, including meals and sleep as well as leisure time. In other words schedule as many non-work activities as possible but do not plan work on projects in the calendar.
Afterwards, fill your calendar with the work on projects after you have at least worked on the project for half an hour - uninterrupted. The goal is that you can keep track of so called quality work during the week. Summarize these hours at the end of each week and you can see how your quality work hours increase.

I found this idea great to see how my productivity would increase using the metholody described in David Allen's "Getting Things Done". The book "The NOW Habit" is actually from 1989 but it think it's more current than most of the newer time management books telling you about the ABC priority and daily to-do list crap again.
