Anger management does not involve getting rid of all anger, but using anger to enhance your life. We can look at the purposes of anger in both a positive and negative light.
The positive aspects of anger are that you have increased energy, are able to communicate your feelings, able to problem solve and can take charge of the situation.
The negative aspects of anger are that you can have disruption of your thinking, unnecessarily defend yourself, become aggressive and become known as an angry person.
