Well, I have struggled with context since 2 years.
Since the beginning i used usual GTD contexts as David Allen suggested in his book. But there was a problem about action.
OF was and is perfect for project planification but on the rush there is a real heavyness wich blocked me. I finally found the solution. I may say my solution thanks to THINGS and THE HIT LIST .
The solution is tags. As OF accept searching on the rush every where instead of doing @Call, @Wait, @ Out, @Mac, and so on i could do :
@Today, @Na (next actions), @Scheduled, @Someday (suspended), @Delegated (for things i am waiting from others).
I usually write my tasks like this
@Call John Ridlesteam for negociating our contract / Na send the contract.
The RESULT is incredible. It's much better. I can work efficiently and now i have the tiem reserved for my PROJECTS (Thinks, plan, erase, add tasks...) which is intellectual, and ACTION where i rush act and use regularly the function FOCUS which is indeed a great Idea.
What is interesting with this way of doing things is that i am focus on what i have o do at the moment and nothing else and i can work project by project very fastly. Hope this will help some of you
