That's what i tell my kids all the time. Don't fantasize about being a pop star. you have no freedom, you do as you're told. These people are not freewheeling rebels doing their own thing. Everything they do or wear, every dance move they do is what they are told to do by consultants. No more, no less. It even applies to their dating relationships. It's all fake. These relationships are scripted.
There is wealth and fame to be gleaned, but at the price of one's soul.
