Do you want to know how you can tell when you are famous at a level above anyone else? It really has nothing to do with money or if people know your name. Sure, that is one level of fame. Everyone knows who Paris Hilton is and she has made some money, but, she is just one of many fish in the celebrity sea. Sure, she is a little more diseased than the rest of the fish, and her colors are not as bright as the rest of the fish, but she is just there swimming with all the rest of the wannabes.
JK Rowling also knows what it is like to be famous. She is known all over the world and has gobs and gobs of money. So, what makes her different than all of the other celebrity fish swimming in the sea? She has world leaders lined up like a kid at Comic-Con wanting her autograph in books not only for their own children, but for themselves. According to The Telegraph, at a dinner prepared by Jamie Oliver, it was not Jamie who was the star, but instead, JK Rowling who sat there patiently and signed books for Barack Obama, the Russian President and his wife and several other world leaders who all stood patiently waiting their turn.
When you can literally stop the world in its tracks when you show up at a party, you have pretty much achieved a level of fame not many people will surpass. The only other time world leaders would be that excited to meet someone would be if they were a lobbyist handing out free money.
