So what should we say when children complete a task—say, math problems—quickly and perfectly? Should we deny them the praise they have earned? Yes. When this happens, I say, “Whoops. I guess that was too easy. I apologize for wasting your time. Let’s do something you can really learn from!

Wow, that's a really good score. You must have worked really hard.

The whole point of marriage is to encourage your partner's development and have them encourage yours.

Just because some people can do something with little or no training, it doesn't mean that others can't do it (and sometimes do it even better) with training.

When you enter a mindset, you enter a new world. In one world (the world of fixed traits) success is about proving you’re smart or talented. Validating yourself. In the other (the world of changing qualities) it’s about stretching yourself to learn something new. Developing yourself.

Don't judge. Teach. It's a learning process.

This is hard. This is fun.
