After watching marriage-advice books catalyze the destruction of my first marriage, I did not think I would find myself reading any more of these books soon. But I heard an interview with Dr Gottman on National Public Radio and I was so impressed that I ran out, bought the book and read it. The thing that makes the book so good is that it is based on rigorous, scientific research (you know, set up an experiment, collect data, look for patterns in the data without inserting your own preconceptions and report it). Although I found that most of Dr. Gottman's findings were not particularly surprising, I still found the book to be extremely useful because out of the many possible things a person could do to improve their marriage, this book tells you which ones really matter. The book also gave me a good sense of the problems that are encountered in happy marriages. For example, about 60% of the conflicts that happily married couples have are unresolvable (perpetual). This fact alone would have helped my first marriage a lot considering all the good will that we burned up trying to solve problems that were not solvable. Dr Gottman found that happy couples accept that these problems are unresolvable and can learn to live with them without damaging their relationship. As an analogy he points out that people with bad elbows can live very rich and rewarding lives as long as they don't make playing tennis a central part of their lives. In summary this is a great book that people who don't like marriage advice books can enjoy (as well as those who do).
