Let's say that you have 100 items on your Inventory lists ( Calls, PC, Action). When you are working in your office, you feasibly could make a call, finish a PC task, or work on an action item. Does this mean that you will need to review all 100 ( combo of paper lists and PC folders) each time you are ready to work on something to ensure that what's most important gets done? I can see where having the items sorted by context could be helpful when you are not in your office and the context could be a limiting factor. I'm not sure I see the advantage of having them sorted by context when the factor is not a limitation?
Secondly, do you combine Work and Life lists (calls, PC, Action, Projects) or keep them separate?
