You know, parenting is so personal. And we're all afraid that we didn't quite get it right. And it feels like the stakes are so high. By we - what if we made a mistake?

I'm a proud strict mom and, you know, I'm really proud of the two daughters I've raised. And I'm especially proud of my relationship with them. We're very close. I think we're good friends.

I kind of - I like my life, I feel I have lots of opportunities. And my parents actually having had such high expectations for me - I would say it's the greatest gift that anyone has ever given me. I complained a lot when I was little, but that's how I feel now. And that's why I tried to do the same with my two daughters.

Genghis Khan decreed religious tolerance for all of his conquered peoples. So I think he definitely would approve of our constitutional protections of freedom of religion. I think he would also approve of the way the U.S. has been able to attract talented people from all over the world.

I'm suggesting that, ironically, the secret to becoming a world 'hyperpower' is tolerance. If you look at history, you see great powers being very tolerant in their rise to global dominance.

I think if you're a 'tiger parent' early on, you don't need to be a 'helicopter parent' in high school.

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.
