Besides getting things done,
GTD is so much fun.
Hooray, now comes the question:
When you have a very big project and you decide to create several subprojects to make the work better manageable... Do you still create next actions for the main project? If you do the slicing in a clean way there should be no need for this because all the moving parts have become (sub)projects in theire own rights. But then you have some hyper-projects without next actions... How do you handle that? And a related question: do you have any structure in your projects list besides just listing all the projects?
