Darrius was born with three fingers on his right hand and one on his left hand．He had to work hard to do things that were easy for others． Every time his classmates tried to help， he would say，"Thanks， but I can do it myself．" He learned to use the four fingers to do different things．

   When Darrius was 10， he told his father that he liked piano（钢琴） music very much． "It's too bad you can't play，" his father said． But the boy took that as a challenge（挑战）．"I will show people that I can，" he said to himself．

   Months later， a neighbour gave him an old piano when she moved away． He taught himself to play the piano and practised for hours a day．

   Darrius's favourite piano music is River Flows in You by Yiruma，a Korean musician．It took Darrius a year to learn it．"I have to come up with my own way with only 4 fingers，" he said．When he succeeded，he felt so proud．Later he was lucky enough to play the music together with Yiruma at a famous concert hall! Yiruma encouraged Darrius to follow his dream of playing his own music， Darrius has made it．And his music is popular today．

   "I may have a disability，" he says，"but I don't let it hold me back from anything．"
