Humans aren't perfect. Sometimes we get sick or behave irrationally, with negative consequences. Although much of our behavior is guided by various social institutions, this formal manner of regulation is less effective than a personally designed system of rational self-management. At a societal level, we eradicated many socially-unacceptable behaviors, but most of us have not achieved this on a personal level. Society entrusts each person to maintain his own personal health, but where does he turn to if he needs help preventing a major crisis or correcting destructive behavior? The author offers an innovative approach solution: rational self-management. It starts with establishing rules for a rational lifestyle. In the beginning, the individual may look to someone else's personal experience and adapt it to his own rules. In the next stage, his actions are analyzed to determine if they comply with the rules he has set. These rules are constantly evolving to enhance his behavior. Finally, implementation of the rules is controlled and results are measured. This rational approach to self-management helps one avoid behaviors that can have devastating consequences, such as drug abuse, crime, and it improves his health and quality of life. Try it. You won't regret it.
