Music can be a great power (力量) to change people’s lives. Regina del Carmen Sanchez, 14, always believes this. The girl from Kansas City, US, leads a hard life. She lives in a small house with her mom and grandparents. Her mom gets a very low pay.

But it doesn’t stop Sanchez’s love of music. She wrote her first song Keep Your Head Up when she was 12. It described the bad situation(情况) at her home, but it also sent the message of hope: “My house is old and poor, but it beats (胜过) being homeless… Love yourself and never give up. You’ll see a better life if you keep your head up…”

It took Sanchez several months to finish the song. Sometimes during a break in class, when lyrics (歌词) came into her head, “I would have to write them down right then,” she told the local newspaper The Kansas City Star.

Jeremy Lillig was a spokesman for Bright Futures, a charity fund. When he saw the video of the song, he was moved. He shared it through social media (社交媒体). The fund has provided money for poor students in Kansas City.

Now Sanchez often plays the song in public. “I want to help people understand what is happening in the world in an easy way,” she said.
