It's one thing to read David Allen's book and be awed by the picture he paints of managing workflow effectively (think "mind like water"), and quite another to try to implement it and become frustrated at the results.
I have met with considerable difficulty considering the context in which I implement it -- I am currently serving in the army, with little time on my hands. There is little time where I can sit down and do work without having to be ready for any sudden instructions to move out. However, I still have a lot of work to complete that fall outside of my national service, and this is where David Allen's book fails to address my issues. His system assumes that one has blocks of "work" time where we can productively select what we should do, but I do not have such luxury.
Having said that, I do not wish to give up on the system, as I have been implementing (albeit sparingly) for at least 2 years now. Therefore, I'm hoping that the readers of this forum can help me:
1. There are often things that come to my head when I cannot take anything down, such as when I'm on the move to my next location or when I am not allowed to carry my phone (which is my corralling tool other than my notebook). Sometimes these come as a torrent so I might have to remember 3 or 4 tasks at one go, and this exactly goes agian David's methodology.
2. I fear that the system is taking up too much time for me. Having to interrupt what I'm doing to formally enter a task into my phone is highly distracting. Besides, when you have 2 minutes to enter each task, and you have about 10 task which come to your head within 1 hour of doing work, that's a total of 20 minutes lost. I also spend 4 hours at the end of each week to do my Weekly Review, and I find that it is too time-consuming what with the very limited time on my hands.
3. With the high-stress, little breathing space environment that I am in, I tend to choose to turn to leisure rather than complete work that might be urgent. Is this because I am unclear of my priorities and thus need to revisit my clarity on my workflow? I feel like I need some time to do just anything I want to do at that point, and if anyone understands this kind of time simply cannot be allocated or planned for; it comes at its own whim and fancy. How should I manage this desire for leisure?
I shall confine my questions to just these three most pressing ones for now, for my post has gotten rather lengthy. Your replies would be most appreciated.
