You just get a bunch of hit songs, you get into drugs, you bang a few bitches and you die at the age of forty.
Sounds like a waste of time.
You forgot the "inspire millions of people", "make billions of dollars", "have fun with your career".

if you call that living 
He's perfectly healthy and still doing concerts, raking in billions of dollars and bolstering nations of fans, has recently released an album, and previously released music that will forever be ingrained in human culture. But sure, that's
not living.
Everything you've said in this thread is blatantly stupid and philosophically forgeted.
