America's growth historically has been fueled mostly by investment, education, productivity, innovation and immigration. The one thing that doesn't seem to have anything to do with America's growth rate is a brutal work schedule.

My friends all say I'm going to be Secretary of State. But I don't see how that would be much different from the job I have now.

The tallest building in the world is now in Dubai, the biggest factory in the world is in China, the largest oil refinery is in India, the largest investment fund in the world is in Abu Dhabi, the largest Ferris wheel in the world is in Singapore.

In one week, I went from being a girl who owed a guy thousands of dollars - my manager Anthony was paying for my outfits, paying for my food; I was sleeping in his parents' basement - to taking meetings with every major label in America.

I don't have a telephone. If I had a lot of money, I wouldn't have one.
