Born to be successful?

"When people succeed, it is because of hard work. Luck has nothing to do with success."
Luck has nothing to do with success?I think that's not exactly right.We usually heard about that "Wow that guy was so lucky that he become so successful."All we have to think is how to prepare for every chance.Edison -- the man who invented electric light,said "Success equils to 99% hard working plus 1% luck."We said he is so modesity,he thought he was so lucky to find the best material.This kind of works sometimes failur because of too much time and money with no new finding.After all the most important is hard work.Luck simetimes is not so nessisory.But with no hard working,no metter how lucky the guy is,he couldn't be a real successful person because he is nothing.He don't have the 99%.Scientists tody,just seldom of them can be known by public.Why? Maybe those unkown scientists just waiting for the 1% luck.
