If we want to improve our lives, willpower is not a bad place to start. It has to be noted that willpower is like a battery. When used, it slowly gets depleted. You can see that on college campuses, during the final exam period. Students fill their heads with facts and formulas, pull all fighters, and push themselves to study hard. However studies show that these efforts come at a cost. During the final exams, many students seem to lose the capacity to control anything other than their study habits. They seem to smoke more cigarettes and have more emotional outbursts. They skip showering and rarely make an effort to change clothes. Dear god, they even stop flossing. People who use their willpower seem to run out of it. And that's not all. Trying to control your temper, stick to a budget, or refusing that slice of cake, all draw from the same source of strength. This means that if you turn down the dessert, you'll be more likely to get angry. And if you manage to control your anger, you're more likely to overspend and not stick to your budget. Scary!!! But if willpower is limited, are we doomed to fail at our goals? Luckily there are things you can do to overcome your willpower exhaustion and increase your self-control. Willpower is the highest in the morning and slowly degrades over the course of the day, almost like your phone battery.
