The world is a rich, complex place in part because it is filled with diversity. Likewise, your marriage is enriched and complicated by the differences between you and your partner. That isn’t necessarily a bad thing, though. Learn how your differences complement each other. What can you achieve together than would not be possible on your own. Instead of letting your dissimilarities worry you, develop a sense of appreciation and gratitude for how your personalities and abilities complete each other. 

In our marriage, Betty likes rice and I like potatoes. She can never convince me otherwise. Through the years our happiness is not in diversity but in spite of diversity.
