AVOIDING OR REDUCING ANGER
Closely evaluate the situations in which you have become angry.
First understand the initial feelings that you have such as disappointment, hurt, unfulfilled expectations, loneliness, illness, etc. You have to know what is going on internally before you can really identify how and why you are projecting externally.
Honestly assess what role you played in each situation.
You then have to put yourself in a daily planning mode to recognize what is going on inside of you. If you prepare to handle you, it is much easier to handle others.
Have a mental list of positive things to think about daily. Assess value to your list of things so that the importance of those things outweighs becoming angry.
Learn ways of calming yourself. Whether you need to remove yourself from the situation or take time to think before responding. Learn what works best for you.
Learn how to be a more assertive communicator. You can communicate your feelings without exhibiting any aggressive behavior. But always keep in mind that everyone isn't always willing to listen. You will never be able to control that. A person will listen only if he or she chooses to.
Change your thinking.
