Luskin (Forgive for Good
) approaches the matter of couples' harmony by pinpointing forgiveness as the secret to a relationship's longevity. He defines forgiveness as letting go of anger and despair when your partner doesn't do what you want, yet in one example he does suggest ending a totally unsatisfactory relationship. Still, Luskin's steps toward full forgiveness eventually begin to make a lot of sense once the author reminds readers that they made the choice to be with the person they're with, and that their partner is flawed and so are they. Luskin's advice and case histories draw heavily on his own studies at the Stanford Forgiveness Project, which he directs. But since his notion of forgiveness includes such steps as acceptance of a partner's imperfections, recognizing the love he or she gives and committing to the relationship, “forgiveness” seems like a catch-all term for the same advice many other relationship experts offer.
