Procrastination
Procrastination is the practice of carrying out less urgent tasks in preference to more urgent ones, or doing more pleasurable things in place of less pleasurable ones, and thus putting off impending tasks to a later time. According to Freud, the pleasure principle may be responsible for procrastination; humans prefer to avoid negative emotions, and to delay stressful tasks.
The belief that humans work best under pressure provides an additional incentive to postponement of tasks.
Some psychologists cite such behavior as a mechanism for coping with the anxiety associated with starting or completing any task or decision.
Other psychologists indicate that anxiety is just as likely to get people to start working early as late and the focus should be impulsiveness. That is, anxiety will cause people to delay only if they are impulsive.
For some people, procrastination can be persistent and tremendously disruptive to everyday life. For these individuals, procrastination may be symptomatic of a psychological disorder such as depression or neurological disorder such as ADHD.
Therefore, it is important for people whose procrastination has become chronic and is perceived to be debilitating, to seek out a trained therapist or psychiatrist to see if an underlying mental health issue may be present.
