Michelle Obama said it best "when they go low, we go high". With all the good vibration that come from this quote it may be harder than you realize. Humans are naturally programmed to hold a grudge.
I get it hate is taught yada yada...but this is a littler deeper like in your DNA deeper! Stay with me, we are all goal driven naturally and of course society reinforces goals as the greatest thing since sliced bread. Just like any emotions anger is born out of a sort of passion for a goal, revenge. Once you get even you may or may not feel vindicated. However, until you feel you've accomplished something with your anger whether it's peace or getting even, it'll be pretty hard to just move on.
