I think in general terms, this makes a lot of sense. In practical terms, not making lists or limiting them may not be a real world choice. Defining what a list really is, makes more sense. I can go into a meeting and come out with a list of 10 things that need to get done….job security, right? So when it comes to my lists, one item might be “take care of work items from meeting” instead of adding each item to an ever growing list.
