Daily plan and prioritizing
I am glad that you had a victory! Now, with that said, I don't think you need to apologize. Everyone has different degrees of how they wish to plan their weeks and days. I make a weekly action plan following my weekly review and I also create a daily action plan. The key point for me is that they are PLANS and may have to be modified based on constant changing input and priorities. This is at the heart of GTD, at least I think. I also prioritize, but not a rigid A,B,C system because so many things can't be so neatly packaged this way, at least in my experiences. There is no doubt that there are things that will be more important than others, and that one's focus should be on them. But to ignore the magnitude of other issues and people you work with is laying the foundation for disaster in the long run. Sure, there may be five new work items that show up at your door, and they may be more your colleague's priorities than yours, but if you are too rigid (I'm not saying drop what you are doing now) and label so many of these as "B" or "C" items, and you only work on your "A" items, you won't be much of a team player and it might, just might, come back to haunt you...
Just my thoughts. There is nothing wrong with adding the level of structure to your day that makes you the most efficient. Many people thrive on immense levels of structure (actually, I am one of them!). Just don't be too upset if your best plans get torpedoed throught the day. Some days -- this never happens. Other days -- oh boy! :shock:
Best to all,
