    Billy Dengler, a 14-year-old boy, is in the eighth grade. A month after he was born, Billy’s mother, Terri, noticed that his eyes weren’t quite as big as a normal baby’s. She took Billy to the hospital, and the doctor said Billy would never be able to see.

Although Billy can’t see, he has never let that hold him back or make him different. Billy began teaching himself computer programming by using a screen reader when he was just seven years old. He is a certified Google developer （谷歌认证开发者） now. Google even tried to offer him a job when he discovered a problem in one of its systems, but Billy wasn’t old enough.

Billy’s dream school would be Stanford University or MIT, where he could get a very good education in computer science. After he leaves school, whether he will go to work at a company like Google or design a software company of his own is still to be decided. However, he says he will be sure to do something great.

“It’s a sighted world,” Billy said. “You can’t let anything get in the way of your dreams, and if you do that, you can’t move forward and make your dreams come true.”
