How is Musician's life better or worse than that of other people?

Anyone might once at least think about becoming a famous musician or actor. Their life looks happy and luxurous, with a lot of money and fame; also, they are being an idol of the young people. They enjoy their life and get the interest of various media like TV shows, entertainment magazines and reporters. I think that they'll be happy in their life, because they do what they want, they don't need to study, and they someimes easily earn money from different various ways. However, in some cases they are not. Their life always follows from a busy schedule and they don't have time to rest. Also, paparazzi trace them, so when they go outside, they need to hide or dress up to appear like other people. Furthermore, they get pressured by an obsession to maintain their fame. Unfortunately, some entertainers who lose their popularity get in the blues so that sometimes their life suffered from mental and psychological problems. That shows a contrasted case of them, but I think that their life is generally hard. -Moon-
