If you worry less about what people think of you, you can pick up an astonishing amount of information about them. You no longer leave conversations wondering what just happened. Other people's minds and motives are finally revealed.

The French believe that kids feel confident when they're able to do things for themselves, and do those things well. After children have learned to talk, adults don't praise them for saying just anything. They praise them for saying interesting things, and for speaking well.

There are no soul mates. Not in the traditional sense, at least. In my 20s someone told me that each person has not one but 30 soul mates walking the earth. (“Yes,” said a colleague, when I informed him of this, “and I’m trying to sleep with all of them.”) In fact, “soul mate” isn’t a pre-existing condition. It’s an earned title. They’re made over time.

The French aren't perfect, but they have some parenting secrets that really do work.

French parents are very concerned about their kids. They know about pedophiles, allergies, and choking hazards. They take reasonable precautions. But they aren't panicked about their children's well-being. This calmer outlook makes them better at both establishing boundaries and giving their kids some autonomy.

By your 40s, you don't want to be with the cool people; you want to be with your people.
