The most successful hyperpowers are the ones where there was actual intermixing. Tang dynasty China was Chinas golden age, and contrary to what I was told when I was growing up, Tang China was founded by a man who by todays standards was no more than half Chinese. It was a mixed-blood dynasty that pulled in "barbarians" from the steppe.

There are all these new books out there portraying Asian mothers as scheming, callous, overdriven people indifferent to their kids' true interests. For their part, many Chinese secretly believe that they care more about their children and are willing to sacrifice much more for them than Westerners, who seem perfectly content to let their children turn out badly. I think it's a misunderstanding on both sides. All decent parents want to do what's best for their children. The Chinese just have a totally different idea of how to do that.

The Chinese model calls for giving your kids very little choice - and I've come to see that you can go too far with that. On the other hand, I also believe that Western parents sometimes give their young kids too much choice.

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.

Westerners often laud their children as 'talented' or 'gifted', while Asian parents highlight the importance of hard work. And in fact, research performed by Stanford psychologist Carol Dweck has found that the way parents offer approval affects the way children perform, even the way they feel about themselves.

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.

Be modest, be humble, be simple.
