I am struggling to understand the concept of next action as it relates to a task within a project that cannot be completed in one day. My confusion is over if next actions need to be completed within a single day or if they can extend over a couple of days...weeks. For example, I am drafting a procedural handbook for my team that is very detailed and requires a lot of thought. Should I be re-tooling my next actions to focus on each section (chapter) of the handbook or should my next action be, "write first draft of handbook"? With my other work responsibilities, I cannot work on these tasks or the project each time. I have been trying to use GTD methodology in my tasks, but I keep falling off the wagon and relying on my brain to remember everything. Thanks for any suggestions or recommendations that could help my organize these actions.
