However, do we do anything in life that is not project related?
Hereafter I will push a bit you question...
Yes for most of them. DA consider as "project" every result of more than one task which can be obtained within one year.
Every actionnable project must have at least one next action ie the first very next action to make it happens...
Some next action has no projects relatives. For example a single action list of task : for example Buy some bread, sort papers
However the answer is not obvious. Theses given tasks could be part of a project for example : "Buy some bread" could be part of a project call
Go shopping on Saturday and "sort papers" could be a very next action of :
tidy up the entire office for 2024... It depends on your Horizons thinking... As David said how much do you have to take altitude to be quiet if I remember well and formulate with my own word.
So as you see and as David said We dont have problems we only have projects and most of the time a next action can be part of a project. An average people has about 50 to 200 projects. Some have much more. I confess I have for now 44 projects I have to finish until December 31. But I also have 120 in a someday folder and 150 cleaned project to remember, I have finished...
Be aware that the very next action can be an actionnable task (a call, a mail, something to do o your computer = what GTD call a context)
Or a non actionnable stuff you have to follow it and make it happen later; for example Waiting for Paul 2024 budget (attending 2023 Dec 15th)
This is why some software like Omnifocus or Nirvana has a project list on one hand and on the other a list of next action which can seems to be confusing sometime. This is why they are so well made for GTD
These very next action are nothing but choices you make using GTD criteria (context, time, energy, priority) and Horizons of focus.
