I say 'I love you' to my daughters every day.

Both of my girls have very high self-esteem because they were both able to master certain things; I should think that's good for their confidence.

For my senior prom, my father finally said I could go - as long as I was home by 9pm! That was around the time that most people were heading out. When I was little I was so mad at them all the time. Why can't I do this? Why are there so many rules? But looking back now, my parents gave me the foundation to have so many choices in life.

Western parents worry a lot about their children's self-esteem. But as a parent, one of the worst things you can do for your child's self-esteem is to let them give up. On the flip side, there's nothing better for building confidence than learning you can do something you thought you couldn't.

A lot of parents today are terrified that something they say to their children might make them 'feel bad.' But, hey, if they've done something wrong, they should feel bad. Kids with a sense of responsibility, not entitlement, who know when to experience gratitude and humility, will be better at navigating the social shoals of college.

The fact is that Chinese parents can do things that would seem unimaginable-even legally actionable-to Westerners. Chinese mothers can say to their daughters, "Hey fatty-lose some weight." By contrast, Western parents have to tiptoe around the issue, talking in terms of "health" and never ever mentioning the f-word, and their kids still end up in therapy for eating disorders and negative self image.

Once you get to the Enlightenment, the way that powers get to be hyperpowers isn't just by conquest. It's through commerce and innovation. Societies like the Dutch Republic and the United States used tolerance to become a magnet for enterprising immigrants.
