Procrastination is the act of unnecessarily and voluntarily delaying or postponing something despite knowing that there will be negative consequences for doing so. It is a common human experience involving delays in everyday chores or even putting off tasks such as attending an appointment, submitting a job report or academic assignment, or broaching a stressful issue with a partner. It is not always associated with stress. It can also be during the aftermath of stress or a stressful event. Productivity is low during times of health issues. It is often perceived as a negative trait due to its hindering effect on one's productivity, associated with depression, low self-esteem, guilt, and feelings of inadequacy. However, it can also be considered a wise response to certain demands that could present risky or negative outcomes or require waiting for new information to arrive.
