I am "newly committed" to GTD, having read and implemented to a casual degree in the past - I have recently been promoted to a position that promises to challenge every past concept I held about organization. I'm trying to figure out how I can fit a system into a lab coat pocket that enables me to travel light (those pockets have to hold a lot of other stuff as well....), capture new assignments and have next actions available at all times. I will be spread between different locations, with only occasional access to my desk and computer. I'm a pen and paper geek, so I've purchased some small Moleskines and a sampler from Circa (I was thinking of using the DIY templates), all are great -- but I just have to think through the system. Any "ultralight" concepts out there?
