The idea behind the Olympics games is that you wouldn't win huge prizes or gain a lot of money, because you are an amateur who is naturally gifted with skill in your sport. It shouldn't be rigorous, continued training, it shouldn't be for the glory of the nation, it shouldn't define an athlete.
The Olympic games is no different from Christmas: there were good intentions when it was started, but it has devolved into commercialism and a bastardization of what the original spirit was.
