On to the next task...
The way I work is to get things off my plate as soon as possible and move on to the next task. The problem is it is now filed in the back burner of my mind. It is still hovering in the background somewhere, but I've completed the work, done whatever I needed to do with it and diarized whatever needed to be diarized and moved on until I need to know it again. My boss may come out a month or so later and ask me questions about it and sometimes my mind initially draws a blank. I need a minute to go back and check and then I am completely up to speed again. I find with the volume of work admins deal with throughout the day, week and month, we need some system to keep things straight. For me, the thing that helps is to document everything . I put items in my calendar as a reminder, but the problem with calendar reminders is unless you know which day you put it on or what you named it, you can't easily find it. For each meeting or event, I create what I call a meeting sheet.
