I have one more question about deadlines. I understood that GTD assumes no deadlines. But what is Weekly Review process then? As I think Weekly Review is a planning process when you take Next Actions for all of your Projects, prioritize them and assign one week deadline till the next Weekly Review? Is it right?
If you have only 20 tasks per week it's Ok to scroll all of them daily and keep an eye on all of them. But what if you have 50-60 tasks per week and what if you find yourself on Friday with 5 tasks to complete that turned out to be 2 hours of work to complete when you have 30 minutes till the end of the workday - move the tasks to the new week? Isn't it a poor planning process when you could put deadlines on all the tasks and notice that they require additional attention in the middle of the week? Any ideas?
