The most successful hyperpowers are the ones where there was actual intermixing. Tang dynasty China was China's golden age, and contrary to what I was told when I was growing up, Tang China was founded by a man who by today's standards was no more than half Chinese. It was a mixed-blood dynasty that pulled in 'barbarians' from the steppe.

I saw my parents come over. They were immigrants, they had no money. My dad wore the same pair of shoes, I had some ugly clothes growing up, and I never had any privileges. In some ways, I think the person that I am now, I think it's good that I had that kind of tough upbringing.

Some people don't need parental commitment, they will still come out great, but for others, parents can be critical in providing moral and academic guidance.

I sort of feel like people are not that honest about their own parenting. Take any teenage household; tell me there is not yelling and conflict.

I write about people who are usually damaged or neglected by society finding each other and forming relationships that are quite extraordinary and in some cases life-saving. I've had a few of those relationships, which I value highly.

I love to travel with my family or my two best friends because I completely trust them. I forced my two best friends into learning to scuba dive with me in Sri Lanka - it was amazing but also hideous because we were learning in very difficult seas.

If a guy isn't in a position to fight for a world title, or if he's not in a place where I can intercept his road to the title, don't offer him to me. I'm not in this to just fight guys for the sake of fighting. I'm not in this to make friends with the people who work in the organization.

I would not say that my relationships are becoming shallow; if anything, some of them are really being tested in a way that I'm so thankful for my friends that call me and still want to talk.
