She Walked Through Fire

    On Thanksgiving weekend, the Heffelmire family gathered for a meal at their home. After dinner, the family went down to the finished basement to relax except Charlotte's father, Eric, who was in the garage to fix his truck．

    Around 8 p.m., Charlotte decided to check on her dad. She walked through the kitchen. When she opened the side door to the garage, black smoke rose up into the kitchen. She could barely make out her father lying on his back, trapped under the truck. He'd removed the front passenger-side tyre and raised the truck on a jack（千斤顶）. The truck had slipped off the jack, and now the whole weight of the wheel was on his chest and shoulders．

    Charlotte ran to the front of the truck and struggled to lift it. Eric was still conscious, and he yelled, “You got it! One more try!” She tried again and was able to tip the truck backward just enough for her to pull her dad by the shirt with both hands from under the truck．

    She dragged him across the garage and 20 feet down the driveway. Then she ran back to the garage, which had burst into flames. “I was afraid the car was going to explode,” says Charlotte, so she climbed into the truck, which faced forward, turned the key, and pressed the gas pedal（油门）. The car slowly rolled out, the metal wheel scratching loudly against the concrete．

    Safely on the driveway, Charlotte stopped the truck and ran back to the basement. “There's a fire! Everybody get out!” she yelled as she picked up her three-month-old niece and ran out. Outside, she handed the baby to her mom, and then ran around to the burning garage. She picked up a garden hose（水管）and sprayed the fire while calling 911．

    A few minutes later, firefighters and an ambulance arrived. Charlotte was treated for second-degree burns on both her feet and face. Her dad had injuries on his chest and shoulders, as well as minor burns on his face. The garage and the house were damaged but the family survived．

    The Heffelmires are staying in an apartment while their house is rebuilt. “Charlotte is a remarkable kid,” says her dad. Charlotte, however, simply says, “ I was saving my family and my house. I wasn't going to let my dad die.”

    Growing up in one of the poorest communities with most crimes in Los Angeles, US, being raised by a poorly-educated single mother and attending the worst-quality public school, not many people expected much of me, so I chose to expect something of myself.

    On my 12th birthday, I bought a poster of Harvard University to hang in my room. Being at Harvard became my dream: I saw myself attending class in Sanders Theater, studying in Widener Library and eating in Annenberg Hall. Driven by this dream, I kept studying hard. I'd begin my day by asking myself these two questions: “What do I want in my life?” and “Are the things I am doing today going to get me closer to that life?”

    Asking myself the questions gave me the courage to ask over 50 Harvard, students for advice on my application essays; it gave me the energy to study just one more hour on my SATs when others were asleep; and it gave me the determination to apply for just one more scholarship when already refused many times. Moreover, reminding myself of my goal each day made it easy to say no to the same choices my friends made, because they would never get me closer to my goal. I found that even being poor could not take away my power to decide what I choose to do with my life.

    Every day I could feel myself getting closer and closer to my goal as my writing got better, my SAT score increased, and my scholarship offers started coming in. On March 31st, 2011, an email arrived from Harvard. The first word was “Congratulations!”. Tears of joy filled my eyes.

    Who you are today is the result of the decisions you made yesterday, and who you will be tomorrow will be the result of the choices you make today. Who do you want to be tomorrow?
