When faced with a challenge, happy families, like happy people, just add a new chapter to their life story that shows them overcoming the hardship. This skill is particularly important for children, whose identity tends to get locked in during adolescence.

We no longer just take religious identity from our parents, so what's going on? Why are people going to this series, why are people reading so many books about religion? It's because they want answers. The answers are no longer just passed down from generation to generation. It's harder for people. In effect, you have to roll up your sleeve and ask the questions. But if you do it, if you forge your own identity, it can be much more personal and much more meaningful to you.

The bottom line: if you want a happier family, create, refine and retell the story of your family's positive moments and your ability to bounce back from the difficult ones. That act alone may increase the odds that your family will thrive for many generations to come.

Everybody has heard that family dinner is great for kids. But unfortunately, it doesn't work in many of our lives.

Knowing more about family history is the single biggest predictor of a child's emotional well-being. Grandparents can play a special role in this process, too.

One day, my daughter Tybee came to me, and she said, ‘I have so much love for you in my body, Daddy, I can’t stop giving you hugs and kisses. And when I have no more love left, I just drink milk, because that’s where love comes from.’

Love is a story we tell with another person. It's cocreation through conarration. When you hit bumps in the road and challenges, you write a new chapter in your story together. Love is the constant act of revising and retelling your own story in real time. You don't do it by yourself. You do it with someone else. The only way you do that is to talk to each other and create a shared narrative.
