In actual life and on TV sometimes we get to know some handicapped people achieving great success which is hard to attain for many of the healthy. Everyone has unlimited potential in some aspect. But it lies dormant in most people. Only those with stubborn determination can fully or partly realize their potential. Some of the handicapped can hardly put up with being looked down upon. They rise up to fight against the social prejudices with their achievements as weapons. They earn the dignity they deserve. So we may say that unluckiness can become a motive force to move forward.
