Adrian’s "Amazing Race" started early when his parents realized that he, as a baby, couldn’t hear a thing, not even loud noises. In a special school for the hearing-impaired, he learned sign language and got to mix with other disabled children. However, the sight of all the disabled children communicating with one another upset his mother. She wanted him to lead a normal life. (33) Then she sent him to private classes where he learned to read lips and pronounce words.
    Later on, (34) Adrian’s parents decided to send him to a regular school. But the headmaster said regular schools couldn’t take care of a special needs student. His parents were determined to take the risk and pushed him hard to go through his work every day because they wanted to prove that, given the opportunity, he could do anything. Adrian made the grade and got accepted. It was a big challenge.
    The pace was faster so he had to sit at the front of the class and really pay attention to the teacher, which wasn’t always easy. But he stuck to it and did a lot of extra work after school.
    The efforts made by Adrian and his parents paid off. Adrian graduated with good grades and got into a top high school. He also achieved a lot in life outside school. He developed a love for the outdoors and went to Nepal to climb mountains. He even entered the World Yacht Race—being the first hearing-impaired Asian to do so.
    (35) But none of these achievements would have been possible without one of the most important lessons from his mother. "If you believe in yourself and work hard, you can achieve great results," she often said.
