It’s important to take care of yourself. And practicing forgiveness actually takes care of you more than whoever it is you should forgive.
Holding on to anger, grudges and resentment affects your health, not the jerk you feel it towards.
Forgive, and forgive often. I write this for myself as much as anyone reading this. It’s all about remembering that it’s far more important to feel ease and happiness than it is be right or superior.
Stuart Wilde wrote “To win a moral victory at the expense of your sanity is dumb.” Because, so what if you’re right if you need hold on to anger to be so. Anger will eat away at you, regardless of how superior you think you may be.
Practice forgiveness. Leave the jerks to muck around at their own level.
