Procrastination is a type of behavior which is characterized 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 an individual, procrastination 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. These combined feelings can promote further procrastination. While it is normal for people 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.

The word itself comes from the Latin word procrastinatus: pro- (forward) and crastinus (of tomorrow). The term's first known appearance was in Edward Hall's Chronicle (The union of the two noble and illustre famelies of Lancestre and Yorke), first published sometime before 1548. The sermon reflected procrastination's connection at the time to task avoidance or delay, volition or will, and sin.
