As the Buddha once said, holding on to anger is like grasping a hot coal with the intent of throwing it at someone else; you are the one who gets burned. So, if it helps, think of this exercise as a purely selfish one—one that will help you feel better and move on—rather than as something that you are doing for the sake of the person who wronged you.
The objective is to write—but not send—a letter of forgiveness to someone who has hurt you. It may help you to note that this is one of the more difficult exercises since most of us can't bring ourselves to let go of the anger we feel at someone who's treated us unfairly. And yet, as numerous findings show, holding on to anger and resentment hurts us more than it hurts the others. So it will be worth your while to complete the exercise even if you don't feel up to it.
