Prioritizing for me is what are my goals for the day, what do I need to accomplish today, what do my superiors need me to accomplish today, what needs to be accomplished for the office. What of those three are the most important? I get to, if my superior needs something by the end of the day, that will probably be my primary task. If I've got the stuff kind of piling up on my desk and there's nothing urgent or requiring real focus from my boss, then I'll work on my pile of stuff and make that the priority. It can change in a given day, I suppose. Once I learn the system, I'll have a good idea of what on a daily frequency what needs to be done versus the things that come in and need to be prioritized immediately above everything else. I have a good sense of those kinds of special projects or those kinds of changes. I try to be adaptable. You can organize, you can plan, but you still need to be adaptable so you can meet your goals and change your plan if needed.
