There is a difference between having too much work and therefore delaying something, and problematic procrastination. Those who have too much work have to make choices and thus change certain tasks from one deadline to another. Those who postpone tasks either know how to set their priorities (but fail to communicate them properly), or have difficulty in setting priorities and are therefore finding it difficult to complete things.
