OK so you need to classify your tasks in two ways:
Is this task Important?
Importance means: does it help you deliver against your strategic or long term goals? If the answer is yes, then it's important, if not, then it isn't.
Is this task time-bound?
This means: Does this task have a specific due date or time? If it does, it is time bound and therefore urgent.
You then use the matrix to decide where it fits:

You should be spending at least 50% of your time doing stuff in quadrant 2. Don't do anything in quadrant 4. Try and delegate quadrant 3 if you can. any task that takes less than 5 mins, just do.
