20．That Rashema Melson graduated at the top of her class surprised few people at her high school in Washington，D．C．But that she maintained a 4.0grade point average and is heading to one of the nation's top universities while living in a homeless shelter never fails to amaze anyone．It is truly an inspiration．
Eighteen-year-old Melson knows that the story seems improbable，especially for someone growing up in one of the hard parts of the nation's capital．"Life is not fair，but despite that difficult reality，you must keep striving through the pain and tears，"she said in a graduation speech at Anacostia High School．
Melson's father was killed before her first birthday，and for the past several years，she has lived with her mothe and three brothers and sister in a homeless shelter．Melson said she considered the shelter a place to stay in，but not a home．"There is no furniture，and no refrigerator．It's just a place to stay in until you get where you want to be，"she told the reporter．Because of a lot of noise at the shelter，Melson found it difficult to do her homework．That caused her to head to school every morning around 7：00a．m．and stay for the next 13hours，taking honors courses and competing in track．But Melson rarely spoke up about her family's situation nor did she ever complain．
"I know that people look up to me because I always try to be the best example，"she said．Melson said she hopes to study medicine science at Georgetown，although her dreams involve having her own room to study，as well as a place to shower safely．"Never be afraid to go after your dreams，and regardless of the negative word that has been said to us，beat the obstacles and let the sun shine，"she told her fellow graduates．"Each step we take is paved with possibilities．Now go and unlock the door to your future．"
