I'll go with the main group:
Ben has no clue. Journalist might be cool?
Zach would love to be a musician. Or a comic book artist. Both!
Nate is totally gonna be an actor one day. Or will he?
Bryan's easy. He's aiming to be a star quarterback in a popular team.
Carlos doesn't have a dream job, but if he can land something that brings financial security, he'll be happy.
Russell doesn't give a shit.
Karina wants to be an artist, open her own gallery, make her own fashion line, becoming a concept artist... She has a lot of art related goals!
Shay hasn't thought about it too much.
Chris wants to work in video games.
