I think tasks should be prioritised by importance and by due date. So that's the way I do it. I just go through all I have and I go to first the level of importance that it has and after I have that. So I can go through the due dates and that's the way I think it should be done. Because that will guarantee that things will be done in the right amount of time and that we can accomplish the most important tasks in the less amount of time.
