We all get angry, it's a natural emotion to have, as long as you utilize it well and effectively. Sometimes, anger is red, hot, and to the point. If we were roasting marshmallows, it would be a great tool to have. When anger is loud, hurtful, harmful and debilitating, is not an effective tool. It serves the Ego, but doesn't serve for fruitful outcomes or purpose with whomever else is involved. Anger, requires management and proper placement and purpose.
Venting in anger serves as an outlet and a positive way to manage your emotions and detox, if you will. Anger as a self-serving modicum, at the behest of another, to attain an agenda or goal, is divisive, disruptive, and uncontrolled, and leads to further problems within the relationship.
Anger is more often a symptom of what isn't obvious...unresolved issues, resentment, frustration, overwhelm, or various life circumstances. Anger, when used as a control or fear tactic, where the angry person is unwilling or unable to manage their own emotions and talk about it, identify their triggers, and work through the issues that trigger them, is non-productive and often widens the gap between communication and getting along and perpetuates those feelings of resentment, more anger, and divisiveness in both you and the person on the receiving end.
Sometimes it is not easy quelling the anger, but understanding the purpose anger has, and understanding that anger is the trigger of other underlying and unresolved issues or circumstances, can help you manage and control it, instead of it controlling you.
Recognizing your emotions, and beginning to recognize your triggers, is the first step to managing anger and reaching conflict resolution. Managing and quelling anger in others can be done with the right approach, the right kind of communication, and with appropriate techniques and strategies that are easily implementable and effective.
