Anger is not a basic emotion. Anger is often a reaction to a pain. It can be a physical pain, like tiredness, hunger, thirst or other pain of the body or mental pain like sadness, insecurities, feeling hurt, feeling unworthy etc. Any of these pain may trigger an anger.
I always avoid scheduling a meeting close to lunch time. I remember when I was mentoring some mentees for a management training program, and they were scheduling for their final project presentation, I always suggested either early in the morning or after lunch time. It was a presentation in front of managers as the panelists. When people are hungry, they tend to become a slightly short-tempered, make wrong judgement or make inaccurate decision.
Anger is an emotion, so it should be managed. Anger that is not managed may become so distructive. E-motion is an energy in motion, it should be expressed not suppressed. To express an anger is to release it and to finish it. It doesn’t mean that if you are angry with someone and you will need to shout at her or him or speak with a high-toned voice. No! It is a destructive way. Someone said when you do that, it will hurt that person and he or she will remember or probably carry that hurt for another six months. It is not to finish the anger then.
What is the way to release this emotion that is not desctructive? It is advised to move away from the situation for a little while. If you stay there, you will tend to react unnecessarily like shouting, blaming, complaining or criticizing. You might not be able to control your words. Ussually you will end it up with regret. It creates another emotion. When you physically move away, your mental focus is switched. It allows yourself to take a mental break. It will become effective to avoid you from reacting. Any emotion is temporary, so you need to deal with it so well in that short period of time. You will surely calm down soon. Just make sure not to react when the temper is rising.
