'But the best advantage is the fact that those who have acquired the habit to commend their enemies is that they do not have hostile feelings and do not feel envious because they are jealous of their relatives' or friends’ success, and are removed from envying their good fortune.' (Plutarch)
Fire burns you, but it can be a source of light and heat too.
When your enemies slander you, when they scream at you or are sly with you, when they gossip about you or wound you; you have two choices:
You can either hit back, clouded with rage. You can fuel the fire and struggle and toss mud and smear the both of you. You can have stress coarse through your veins, you can lose sleep, you can work yourself up, you can respond in a petty tit for tat exchange.
Or you can learn. You can practice grace and poise. You can display virtue and balance. You can be kind, calm, and generous, taking adversity in your stride.
Don't respond in anger, instead be a man of virtue.
Remember, when someone treats you poorly, it doesn't degrade you, it degrades them.
Learn from the exchange. Are there any truths in the accusations? Can you adapt in the future? Are you acting with courage? With patience? With clear thinking?
Imagine then, who you are, your character, when you respond to slander with grace, to anger with objectivity, to a loss of control with a steady nerve, to grandeur with humility, and to underhand tactics with courage.
Your responses forge, craft and refine your character, preparing you to overcome ever harder adversities. All the time whilst your enemies work themselves into a perpetual cauldron of entitlement and rage.
Grace and poise, always.
