It's hard to say something more radical than this. Relationships are revolutionized when two people live by the golden rule. The reason it is so revolutionary is because you and I by nature have an all consuming desire to be treated well by other people. Nobody in this room likes to be made fun of. Nobody here wants to be ignored and treated like a useless person.
Nobody wants to be exploited or taken advantage of.
That means that if everybody in this room lived by the golden rule of Jesus nobody would make fun of any other person here. Nobody here would treat another like he or she were useless. Nobody here would take advantage of someone else. The measure of our love for our own happiness would be the measure of how eagerly we pursued the happiness of each other. It would be utterly revolutionary, especially in marriages and relationships between men and women in general.
