The 30 Secrets of Happily Married Couples by Paul Coleman

Published in 1992, this collection and the research it is based on are both now a bit dated. However, the truths couples will find within have stood the test of time. Coleman effectively takes the best research on couples available at that point and breaks it down into easy-to-understand secrets, each one by itself enough to revitalize a failing relationship. The clear language and real-world examples of what happens to couples who don’t know these secrets make this book a must for any couple looking to improve how they relate to one another. Okay, so they aren’t all really secrets... most anyone you meet on the street could tell you that “Effective Problem Solving” is important to making a relationship last. What makes this collection special are Coleman’s guides on exactly how to put the secrets into practice. Those methods are the real secrets.
