We actually do have real life careers in the game -- Athlete (I actually have a friend who's a former pro athlete), Business, Culinary, Tech Guru, Painter, Writer. About the only ones "out there" careers might be Astronaut and Secret Agent, maybe Entertainer but I've known some of those as well (musicians and comedians).
There were a couple of aspirations added with Jungle Adventure, but I agree we could use more aspirations. I play on Long lifespan so my Sims often have time to do two or even three if they finish the first one when they're a teen. I'm not a big fan of the deviance aspirations, and haven't fompleted either of the Jungle Adventure ones but the rest of them are pretty much fair game for me.
