For me, becoming famous is similar to selling your soul, in the sense that you trade in your privacy in return for being famous and also presumably being rich too. It's like Cypher in the Matrix who wants to be reborn as an important actor in exchange for handing over keys to the Zion mainframe.

Sidenote: The problem with fame is that you can't reverse it. If people know your face, then they know your face. There's no getting away from it.
