Having a little self control can save you from a lot of miseries, adversities, and errors. Self control is all about doing the right thing even when you do not like it. It involves shunning instant gratification and disallowing the demonic side of you from taking over.
Self control is often referred to as willpower. It allows you to direct your attention despite the presence of competing stimuli, and it underlies all kinds of achievement, from school to your workplace. It benefits your relationships as well.
When you lack self control, common sense and logical thinking capacity depart from you immediately. That means that at this very moment, the ‘Do not’ rule becomes weak or even totally ineffective in preventing you from indulging in the act.
