Important, Intriguing and Beautiful

Today in class we spent a good amount of time talking about the different types of learning we each go through.  There is surface learning, strategic learning, and deep learning; deep learning usually happens when we have a question that is important, intriguing or just plain beautiful.
Since this is a class on the family, we were asked to think up three questions that were in those categories.  Here were my questions:

Important: How would you know when your marriage is heading south and how would you recognize the red flags?

Intriguing: How come intimacy is so easy to obtain in the beginning, but so hard to hold on to as time goes by?

Beautiful: How can I learn to love and grow with my spouse through the rocky times when emotion is no longer the driving force?

Although I'm not married myself or have kids, I want to learn all that I can so that when the time comes I am able to be the best wife and mother that I can.  “Motherhood is near to divinity. It is the highest, holiest service to be assumed by mankind.” - Howard W. Hunter
