Just about any discipline that has to do with the body, if you really think that discipline is important, is mostly just a matter of making yourself do it; but forgiveness is not merely a bodily matter. Forgiveness is a matter of the soul, of the heart. Forgiveness is not so easy. On its most basic level, forgiveness means that you will not seek revenge. It means that you are letting go of your right to get even. When you forgive someone, you stop punishing them in your mind. It means that you stop rehearsing in your mind how much they hurt you.
