I use GTD for Collecting, Processing, Organizing and Review pretty stringently. When it comes to doing, I use GTD guidance to select my pre-defined work for the day. Once that selection is made, I transfer those tasks to a a pomodoro technique work sheet for planning my day around pre-defined work. The pomodoro technique also allows for urgent and unplanned work and allows for extra time to do processing and organizing during the day. Anyone see anything inherently wrong with this? I find the two systems to be quite compatible.
