I'm not an advocate or supporter of the social pressure behind women being constantly inundated with messages to "be kind" , "be sweet" or "be nice". When they start slamming adult males with that 'advice', I might consider listening.
Still, maintaining control over our own emotions has advantages Calmness-which is something you manage as opposed to others dictating it to you- has advantages. When we are calm we tend to think more clearly. We tend to breathe more deeply. Our blood pressure and other health conditions are more likely to remain stable. Plans and solutions to problems flow our way in more calm states.
Calmness is a way of standing by you own self. No matter what comes your way, tending to your own needs first is a great way to prioritize your own needs first. Calmness is a powerful fighting stance.
