seems to be true about the weekly review :)
This is a very interesting thread for me and I thank you for having started it.
It has been more than a year now that I (really) started with GTD. Collecting was a piece of cake, came really naturally and easily and already helped me a lot in organizing things.
Processing is still a big stone on my way but I am working on it (reading The Power of Habit from C.Duhigg is helping me to better understand my brain!). Improving...
And reading this thread I got a "click" (even if I have read this thousands of times all over GTD forums, etc) about the weekly review. I do it but very sporadic and it seems this is impeding me to process and do better. Somehow I am blocked with processing because my brain understood that after processing nothing will happen with the "stuff".
I find it amazing how small and really "stupid" details can make you understand something that has been explained so many times before. That is mainly why I read the forum.
Maybe this helps you too: doing my weekly review was very difficult till some time ago, but finally I understood that I cannot set a fix day/time for it every week, as I travel a lot and often on very short note.
What I do now is to set the date and time for the next review when I finish the one this week. So I know what I will be doing next week and when I will be as "calm" as needed to do it. I put it down on my calendar and do it.
What David Allen said about 2 hours, 2 days, 2 weeks and so can be the case for some, but these must be rather very, very determined. Might be a good goal but I doubt it applies to the majority of us.
Good luck anyhow to you and to me too
