Pros: Reaching huge amounts of people through music, possibly changing peoples lives, finacal stablity, sold out concerts, thousands of loyal fans, traveling to places like Toyko; a place where most people their age can only dream of going, freebies.
Cons: As their fame grows; the endless army of teenies [[meh, I won't bother them too much XD]], rarely any personal time or family time, the constanst battle with the press, never really being able to have that normal teenage/young adult life [[but I guess that's a pro too]], tour after tour after tour, you can't go someplace without someone pointing you out.
