     [1] Ashley Power's mother bought a computer for her when she was eight. When she was thirteen,

she was surfing the Internet regularly, but she couldn't find anywhere for teenagers to meet and talk. And

one day she thought, "If I had my own website, I'd make it a really interesting site for teenagers."

     [2]So, when Ashley was sixteen, she launched her own website, called Goosehead. She had no idea

how big a success it would be, but three years later, the site was the most successful teen site in the USA! It was getting 100,000 hits every day, and Ashley had about 30 employees.

     [3] After a few years, the website closed down. Then Ashley, who lives in Los Angeles, was asked

to write a book called The Goosehead Guide to Life. The book is about how to design a website and

start a business. It begins with a section called "All About Ashley," where Ashley tells readers what it is

like to be the boss of a company when you are only sixteen. " I was so happy. But it was crazy in a lot

of ways. I got very stressed. I mean, I was only sixteen - I didn't even have a car! If you were sixteen

and you had your own company, you'd be stressed, too!"

     [4] In an interview Ashley gave advice to teenagers who wanted to start their own business, "Just be
