When people say luck has nothing to do with success, I wonder it is not their intention to deny exsitence of luck, but to encourage. Because luck in fact is a factor that one can not and should not count on, even though we know people who have succeeded have their own luck. It is somewhere, but nobody knows where. It happens sometime, but we do not know when. By contrast, hard work is something that everyone can count on, and as is often the case, hard work might bring luck. Therefore, luck itself is of no hope, and lack of luck should not be an excuse for failure.
