People having a high level of self-control experience better relationships and have higher achievement levels. Lack of self-control is associated with social conflict and low-grade academic performance.
Example: While following a diet regime, a person spends a lot of willpower the whole day trying to avoid junk food, but by the end of the day, all his mental energy has been exhausted, and there is no self-control left, resulting in snacking on unhealthy food.
Self-control is the ability to regulate and alter responses in order to avoid undesirable behaviors, increase desirable ones, and achieve long-term goals. Research has shown that possessing self-control can be important for health and well-being. Common goals such as losing weight, exercising regularly, eating healthy, not procrastinating, giving up bad habits, and saving money are just a few worthwhile ambitions that people believe require self-control.
