I love GTD. Have never been so organized. Well, at least I've never had all my thoughts and ideas down in one place (currently using the awesome omnifocus on my iPad 2, iPhone and iMac... all work seamlessly together). My method includes a routine of Pomodoros (review todos each morning, make a list of items that I want to accomplish in a day, set them on paper in order, and go through them noting each 25 mins with an "X" until that item is done, then onto the next one). The problem is two-fold: first, my todo lists just keep piling up because everyday something new takes priority (this is perhaps the most problematic thing of GTD for me) and I can never finish all my Pomodoros in a day, so they accumulate. My GTD projects, WF, Agendas, etc, are mushrooming like mad... I'm not sure what to do next to get back on track.
