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?

For my senior prom, my father finally said I could go - as long as I was home by 9pm! That was around the time that most people were heading out. When I was little I was so mad at them all the time. Why can't I do this? Why are there so many rules? But looking back now, my parents gave me the foundation to have so many choices in life.

You can't invent Google, Facebook or the iPod unless you've mastered the basics, are willing to put in long hours and can pick yourself up from the floor when life knocks you down the first 10 times.

Everything I've ever done that's valuable is something I was afraid to try.

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.

When I was little, my parents really only wanted me to be a scientist or a doctor; they had never even heard of law school. I think even these days if you were to tell your mother you want to be a fashion designer, or an artist or a writer, a lot of Asian parents would be alarmed because they don't think that's a secure career.

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.
