Priorizing your To Do List used to be a case of ranking A, B or C and then ranking within A, B or C to 1, 2 or 3. It was the A1’s that were to get our attention; and I suspect that you are still struggling to get the A1’s done.
You’ve rewritten your list so that every task starts with an action verb such as call, write, create or decide. Write into your calendar a time slot for all your call items that will take more than 10 minutes. Anything less than 10 minutes, do it now. Complete the same process for your other action verbs items and watch the list disappear.
