A few years ago, I remember reading a talk by President Boyd K. Packer, President of the Quorum of the Twelve Apostles, and for me, it was one of those things you read once and remember for the rest of your life:
"My young friends, there is much happiness and joy to be found in this life. I can testify of that. I picture you with a companion whom you love and who loves you. I picture you at the marriage altar, entering into covenants that are sacred. I picture you in a home where love has its fulfillment, and I picture you with little children about you and see your love growing with them. I cannot frame this picture. I would not if I could, for it has no bounds. Your happiness will have no ends."
I've spent so much time "planning my own wedding" since I was six (just kidding, maybe like 12) and usually it included things like what flowers I wanted at the reception, or what "our wedding song" would be -- but I think so much of the little details go unnoticed anyway because you're so overwhelmingly happy and grateful for the feeling of love. And for family, too.
