Many GTDers will have heard David Allen talking about falling off the GTD wagon, and most importantly, getting back on again. In the past month or so I would say that I was teetering on the brink of this wagon, barely able to keep a hold on my system and working in reactive mode.
But today I did my weekly review and felt my workload come back under my control. The review is a strange beast - so easy to put to one side and think that it is not as important as all of the other tasks on that list! But it really and truly is the bedrock of the system that keeps all tasks in perspective. Without it (as I have recently experienced), a 'mind like water' is impossible and the weight of the workload starts to wear you down.
Having done my review today, I feel uplifted and more free than I have for a number of weeks.
