参考答案： Some people think that certain numbers will bring good luck to them. Numbers such as six, eight, sixteenand eighteen are regarded as lucky numbers. There are also people who think that their success is related to certain numbers. However, some other people think numbers have nothing to do with their luck. They believe in their own abilities rather than "lucky numbers".
I think it is a person's own business whether he believes in a certain number or not. The most important thing is that he has done the work by himself and has done it quite well. As to the belief of numbers, it's their personal choice.
