I have learned no matter the situation; work, home, or personal when you are upset or angry you should slow your roll. There is no reason to express the full tempo at the moment. It is best to gather your thoughts, feel your feelings and then craft the most gracious response. Slowing your roll and being thoughtful shows you care about the other person, it also shows you had time to self-reflect on the situation.
In life there is always a moment to reflect: why am I feeling this way, am I part of the problem, why am I am so heated or upset? What could I do better, how can I acknowledge the wrong or my feelings and take responsibility for it at the same time?
There are moments where emotions take over and we react, that is normal. But if all your emotions, especially the heated are always on your sleeve, it might be time to take a breather and analysis the bigger picture.
