A key question for staying on track with your work is this: what are the results expected of me? Each week, each quarter, and each month?
You need to have a general answer for this, and then you need to translate that specifically to each week and each day.
It works best to define your tasks from those results—rather than starting with the tasks and trying to get to the results. Start with the results and work backwards. That may sound easy, but most of us (including me) all too easily start the other way around—tasks to results.
