Though the cheese factor is high in this book on advice for busy married couples, I think they actually do have a lot of useful information. In retrospect it's obvious that time is not renewable and that we should be focusing on spending REAL, un-distracted time together, but I think people in our society today need to be explicitly told this information. They have tons of quotes dispersed throughout, too, and most of them are great: "Devoting a little of yourself to everything means committing a great deal of yourself to nothing.
"More often than not, we are so busy preparing for the future that we miss out on the moment at hand."
