When there's a good fit between skills and expectations, there's what we call compatibility, and we would expect a good outcome. When there's a poor fit between expectations and the capacity of the kid, there is incompatibility, and that's when we see people exhibit challenging behavior.

You want to teach all kids the skills that are on the better side of human nature: empathy, appreciating how one's behavior is affecting other people, resolving disagreements in ways that do not involve conflict, taking another's perspective, honesty.

People don't scream or swear or pout or sulk when there's compatibility. But most growth occurs when there's incompatibility. When it comes to resilience, when it comes to pulling yourself up when you've fallen down, you don't learn those things when things are going well. You learn those things when you're struggling.

My advice to educators is collaborate with parents; they know a lot about their kids.

We have forgotten that those skills on the more positive side of human nature have to be taught, have to be modeled, have to be practiced.

For a very long time, people have been saying to me, "What if you want to do this approach with every kid?" For a behaviorally challenging kid, you're parenting this way just to help bring the kid's behavior under control and to greatly reduce conflict. But you want to teach all kids the skills that are on the better side of human nature: empathy, appreciating how one's behavior is affecting other people, resolving disagreements in ways that do not involve conflict, taking another's perspective, honesty.

If we're sitting at dinner and there's no conversation going on because everybody's got their head someplace else in their iPhone, that's a family problem that needs to be solved.
