At times in my life, I’ve been mistreated. And, really, that’s perfectly alright. Don’t we all experience that at some point or another? Just as we need a certain degree of familiarity with sadness in order to appreciate the fortune of happiness, we need to encounter people who disservice us in some way, shape, or form in order to recognize and be grateful for those who do good by us. So I forgive those whose actions have hurt me because without them, I would neither be conditioned to overcome pain nor embracing of those whose intentions are pure. Besides, harboring feelings of resentment and animosity accomplishes little but to weigh you down and make you bitter.
Forgive and forget. Or, you know, just forgive if forgetting is not plausible.
There is an ample amount of good to make up for the bad if only you look hard enough.
