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.

Managing through ambiguity can be difficult for even the most experienced leaders. Defining a clear set of goals for your team demonstrates that there is an end in sight. However, it's crucial during this time to move through the transition in phases.

I'm really thankful and complimented when people come to me and say, thank you for the great times for all these years. But I don't think about it as being a leader.

There should be no effort, consciously or otherwise, that will lead to the erosion of institutional credibility and authority.

I think we all have to ask ourselves, as leaders, do we have the right processes in place for complaints to be filed and for people to feel protected?
