I disagree with him because if somomeone keeps thinking about the past, he will never improve the abilities he has. All of us came to this world with something we cannot change, such as colore or hight. However, everyone has some abilities inside, if he works on these abilities, he will reach a place or a position that everyone would love to achieve. My openion, just look to the positive side and avoide the mistakes we have done before. Life is a full of many examples, many scientist were blind and they overcame such this disability.
