Never complain or make excuses. If something seems unfair, just prove yourself by working twice as hard and being twice as good.

I am definitely a Type A personality, always rushing around, trying to do too much, not good at just lying on the beach. But I'm so thankful for everything I have: wonderfully supportive parents and sisters, the best husband in the world, terrific students I love teaching and hanging out with, and above all, my two amazing daughters.

I once won a second prize in a history concert. My parents came to the ceremony. Somebody else had won the prize for best all-around student. Afterwards my father said to me, 'Never, ever disgrace me like that again.' When I tell my Western friends, they are aghast. But I adore my father. It didn't knock my self-esteem at all.

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.

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.

I do play tennis, but I don't really like competition. I'm supposed to be so intense, but I hate competition.

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.
