I was just discussing anger, grudges & repentance with a friend last night over dinner."I wish I had not held that anger, you have to let things go or you just prevent yourself from doing what you know is right."
One thing I’ve noted: in a lot of true crime stories, the people who hold onto their hates & disappointments the longest & hardest often develop issues related to those feelings down the road- divorces, estrangements, alcoholism & substance abuse. Sometimes suicides. It’s like ugly seeds growing into awful trees.
So I actively try to minimize the amount & intensity of my grudges, but it’s a struggle. It occasionally surprises me how much “small stuff” I still “sweat”.
