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.

I sort of feel like people are not that honest about their own parenting. Take any teenage household; tell me there is not yelling and conflict.

My youngest sister, Cindy, has Down syndrome, and I remember my mother spending hours and hours with her, teaching her to tie her shoelaces on her own, drilling multiplication tables with Cindy, practicing piano every day with her. No one expected Cindy to get a Ph.D.! But my mom wanted her to be the best she could be, within her limits.

Every day that you don't practice is a day you're getting worse.

When I'm not the Tiger Mom, I'm a professor at Yale Law School, and if one thing is clear to me from years of teaching, it's that there are many ways to produce fabulous kids. I have amazing students; some of them have strict parents, others have lenient parents, and many come from family situations that defy easy description.

I worry that by losing my temper so much and being so harsh and yelling so much that, by example, I will have taught my daughters to be that way, and I'm now constantly telling them not to do that.

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.
