I have customized this format to my needs, I have the following lists:
Personal
Work
Someday / Maybe
List per big project I have (either personal or work related)
On top of these lists I have several tags according to where I’m suppose to do them:
@Office
@Call
@Errands (i.e. by groceries)
@Internet
@Email
@Home
@Blog
Each task can have additional tag
na (Next Actions) – the task is not dependant on other task to complete.
wait (Waiting For) – other task need to be completed before I can finish this task
