I look at these and believe they apply to anything you do in life.
Clearly some are meant to be husbands and some are not. Once you decide to become one you need the desire to stay true and the durability to withstand the rough spots. Finally you need the Courage to risk it all on being a great husband. The odds are clearly against it so courage may be the big quality.
You can apply this to work and so much more.
It's a good life...
