Procrastination is a type of avoidance behaviour which is characterised by deferment of actions or tasks to a later time. Psychologists often cite procrastination as a mechanism for coping with the anxiety associated with starting or completing any task or decision. 
For the person procrastinating this may result in stress, a sense of guilt, the loss of personal productivity, the creation of crisis and the disapproval of others for not fulfilling one's responsibilities or commitments. While it is normal for individuals to procrastinate to some degree, it becomes a problem when it impedes normal functioning. Chronic procrastination may be a sign of an underlying psychological or physiological disorder.Did the Wikipedia quote above said "psychological disorder?" Oh boy... ;)
