     When other nine-year-old kids were playing games, she was working at a petrol station. When other teens

were studying or going out, she struggled to find a place to sleep on the street. But she overcame these terrible

setbacks to win a highly competitive scholarship and gain entry to Harvard University. And her amazing story

has inspired a movie, "Homeless to Harvard:The Liz Murray Story", shown in late April.

     Liz Murray, a 22-year-old American girl, has been writing a real-life story of willpower and determination.

Liz grew up in the shadow of two drug-addicted parents. There was never enough food or warm clothes in

the house. Liz was the only member of the family who had a job. Her mother had AIDS and died when Liz was

just 15 years old. The effect of that loss became a turning point in her life. Connecting the environment in

which she had grown up with how her mother had died, she decided to do something about it.

     Liz went back to school. She threw herself into her studies, never telling her teachers that she was

homeless. At night, she lived on the streets. "What drove me to live on had something to do with understanding, My understanding was that there was a whole other way of being. I had only experienced a small part of

society," she wrote in her book Breaking Night.

     She admitted that she used envy to drive herself on. She used the benefits that come easily to others, such

as a safe living environment, to encourage herself that "next to nothing could hold me down". She finished high

school in just two years and won a full scholarship to study at Harvard University. But Liz decided to leave her

top university a couple of months earlier this year in order to take care of her father, who has also developed

AIDS. "I love my parents so much. They are drug addicts. But I never forget that they love me all the time." 　　

     Liz wants moviegoers to come away with the idea that changing your life is "as simple as making a decision".
