Anger is an emotion. When we get angry we lose control of that emotion. In order to live by the above principle we must understand what triggers our anger and how we can choose to remove this destructive emotion from our being.
In every confrontation that leads to anger the person or thing pushing your anger button has complete power and control over you.
This simple realization allows you to take back control of your emotions and as such you can now choose to respond to a situation in a positive way rather than react to a situation in a negative way.
