Most people get married believing a myth that marriage is a beautiful box full of all the things they have longed for: companionship, sexual fulfillment, intimacy, friendship.
The truth is, that marriage at the start is an empty box. You must put something in before you can take anything out. There is no love in marriage; love is in people, and people put it into marriage. There is no romance in marriage; people have to infuse it into their marriages.
A couple must learn the art and form the habit of giving, loving, serving, praising -- keeping the box full. If you take out more than you put in, the box will be empty.
The above was found written in the front cover of a book on marriage.
