Why the path of fame and fortune is really not like what you think?

This is inspired by an old thread in Fluther that I’ve found here http://www.fluther.com/35199/have-you-ever-tried-for-fame-or-fortune-how-what-happened/ that asked and talked about the seemingly luscious, inviting path of “fame” and/or” fortune”.
I want to know more.

So to those of you who said that you’ve tried either the “fame” or “fortune” path, and it was not like what you THINK, even that it probably contain more of a pain and craps on its own,
as a passionate and aspiring musician/songwriter myself that admittedly sometimes dreaming of that alluring factors, I really want to know exactly why you think like that, and would really very much appreciate if you could share your own personal experience with trying either that eluding path.

And should I better NOT to ever try to obsess or even chasing that two routes? and as the cliched sayings goes: just “be true to Myself” and my artworks?
What is your conclusive advice on this?
thank you!
