If I want to forgive someone, should I consider following your 20 steps in the exact order in which you describe them?
This process model was not constructed to be a rigid model in which you have to follow the sequence in the exact order. Some of the units will be irrelevant for you and so you can skip them. Sometimes, as you are near the end of the forgiveness process, your anger re-emerges. At that point it may be best to cycle back to the earlier units to once again examine and confront your anger.
