To grow in any virtue is similar to building muscle in the gym through persistent hard work. We surely do not want to overdo anything, including the pursuit of fitness.
Yet, we must avoid underdoing it, too, if we are to continue to grow. It is the same with forgiveness. We need to be persistently developing our forgiveness muscles as we become forgivingly fit. This opportunity is now laid out before you. What will you choose? Will you choose a life of diversion, comfort, and pleasure, or the more exciting life of risking love, challenging yourself to forgive, and helping others in their forgiveness fitness?
