The first thing is love: love deeply. If you have been with a person for a few years, in deep love, and you have experienced all the joys and all the miseries, and still you decide to be with the person, then marriage is okay. Because marriage is only a legal arrangement, it cannot make anything more beautiful than it is. It can only make it ugly, it cannot beautify it. Once it is settled legally, once you start taking each other for granted, things will start going down rather than rising high.
