Anger is a perfectly normal, healthy emotion.  Everybody has triggers, and what bothers one person might not bother the next person.  Anger only becomes a problem when it gets out of control.  If you have a problem controlling anger, steps must be taken to deal with it in a more positive way.  If ignored, high levels of anger may lead to relationship issues.  

For this reason, it's important to learn anger control techniques if you have  quick temper.
