How much work do you have to do before you can do your work?

You know how you have a task you set out to complete, but first you have to look something up. And you have to find those notes you took. So you have to clear away the stack piling up by your computer. And you realize that you forgot to send this in that is due tomorrow morning. Then you are interrupted by some minor catastrophe in the next room. And then you have to take this phone call about tonight's carpool.

And an hour, a whole day goes by and the main part of your work, the part that they are paying you for, is still left undone. Do you just feel like you are treading water?
