Parenting cannot just be one size fits all.

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.

Do you know what a foreign accent is? It's a sign of bravery.

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

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.

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.

When my kids wanted to give up on things, I wouldn't let them, and those are lifelong lessons.
