Real self-esteem has to be earned. I also believe in virtuous circles, like, nothing is fun until you are good at it. It is great if you can instill in children the ability to not give up, to have a work ethic.

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.

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.

I see my upbringing as a great success story. By disciplining me, my parents inculcated self-discipline. And by restricting my choices as a child, they gave me so many choices in my life as an adult. Because of what they did then, I get to do the work I love now.

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.

A Western upbringing tends to stress questioning authority, which is always asking why, why, why.

A lot of parents today are terrified that something they say to their children might make them 'feel bad.' But, hey, if they've done something wrong, they should feel bad. Kids with a sense of responsibility, not entitlement, who know when to experience gratitude and humility, will be better at navigating the social shoals of college.
