I have read the book and have started trying to implement GTD. It is making my head spin.
Project Deadlines. Lets say I have project that needs to be finished on 12/30. None of the underlying subtasks have hard deadlines so, as I understand GTD, I am not supposed to put them on the calendar since they are not drop-dead to that date and can get bumped--a concept I basically get since I have seen myself do it with systems like Taskline. How do you handle this?
This brings me to another point of confusion. Since everything is driven by next actions and since some actions take longer than others, how do you ensure you are not overbooking yourself with committment you have to keep? How to you keep an accounting of the time inventory you have to fill so you do not get over extended? HOw do you know how much more you can take on?
How do you know what to do next since GTD is generally not tied to the calendar or the amount of time involved?
How do you handle the various interruptions that come in during the day? Phones? IM? (E-mail, I basically get.)
I am just completely confused. Plus it seems like it takes so much time to maintain these lists and build these lists that nothing actually happens.
