How does GTD deal with very rapidly changing priorities?
I'm new here and new to GTD. I have always used my own system, which is very list based, and it has worked very well for me... until now. I recently changed jobs and now my role has rapidly changing priorities which I am finding it hard to keep control of.
For example. Normally I would get to work, check my email to see if anything urgent has come in, this takes about 10 mins of scanning my inbox. I then check my lists to see what I need to get done that day, prioritize, and make a start on the next item which needs to be done. Now, with my new job, I am struggling as things come in from left field which I wasn't expecting, some are short ad hoc items, others are quite large and may take me a day or more to complete, but are urgent. These items interrupt my original plan and push my original tasks out of the way, and so I start to feel overwhelmed. My original tasks still need to be done to meet deadlines, but I also need to do the new urgent stuff too.
Any experience of dealing with things like this would be gratefully received.
