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.

I grew up as a fifth-generation Jew in the American South, at the confluence of two great storytelling traditions. After graduating from Yale in the 1980s, I moved to Japan. For young adventure seekers like myself, the white-hot Japanese miracle held a similar appeal as Russia in 1920s or Paris in the 1950s.

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.’

When I was growing up, I, like many Jews, cheered what appeared to be the receding of faith from everyday life. The further religion got from our lives the better our lives would get, I thought, because persecution had been such a burden to Jewish families for generations.

We're in a hyper-connected world, and there's a crisis of connection. The first thing that God says about woman and man in the Bible is that it's not right for humans to be alone. Social media interaction cannot take the place of face-to-face interaction. If anything, it prevents us from doing that. We're staring into our screens for so long that we're forgetting to look at the people directly in front of us.

I'd say my best memory was climbing Mt. Fuji, and the worst memory was... trying to fit my feet into the free giveaway slippers at Japanese schools.
