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

I do think that maybe, even subconsciously, a lot of parents in the West are wondering, have we gone too far in the direction of coddling and protecting - you know, you see kids, sometimes that seem very rude and disrespectful. And the more important thing is they don't seem that happy.

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

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.

I'm a slave to my dogs and go out with them almost every day. They are poorly behaved if they don't run. They really act up.

Instilling a sense of self-discipline and focus when the kids are younger makes it so much easier by the time they get into high school.

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.
