"Getting Stuff Achieved" Sin Bin

Ok all you users of 'Getting Stuff Achieved' (my paraphrase to avoid spamming):

How are we going with staying organised? What is the first good habit to go when you get busy? The weekly review? The breaking down of activities into projects? The getting the inbox to empty?

I find the weekly review is a hard one to keep on top of. As Luke's gmail status reads: "weekly review takes a week"!

Please contribute confessions, hints and questions.
