I've had a PAS for a couple of months now, but I only started using it everyday when I added it to my soft-Journal. I store it on a USB key and it goes everywhere with me
Here's what it includes:
My Life Purpose
My Current Intentions
2006 Goal List (Main and Secondary)
2006 Quaterly Goal List (Breaks down main goals into time chunks)
A Current Projects List (derived from my quaterly goals)
Next Actions List (very much a todo list to complete projects)
and a maybe someday list of things I'd like to consider doing but don't have time to do right now.
I've just finished my 2007 PAS as well, I didn't like only going as far as the end of the year.
Since I started looking at it more regularly it's helped me stay more focused on high level goals, and this has been reflected in my everyday decisions. My decisions are more congruent with my main goals.. and I'm making progress towards them. It has definitely been worth implementing.
