"What can make a marriage work is surprisingly simple. Happily married couples aren't smarter, richer, or more psychologically astute than others. But in their day-to-day lives, they have hit upon a dynamic that keeps their negative thoughts and feelings about each other (which all couples have) from overwhelming their positive ones. They have what I call an emotionally intelligent marriage."
Here's another quote from the book that I love! "The key to a happy marriage is becoming friends. The more you work at being friends, the easier it will be to solve problems as they arise. Marriage isn't devoid of conflict; it isn't simply a matter of communicating more. instead, it is a matter of learning how to disagree and still be friends". (taken from the book The Seven Principles For Making Marriage Work by John M. Gottman PH.D.).
