I think only a few kids really know what they want to do when they graduate....and even fewer actually do it.
My three boys are 21, 23 and 30.
The 30 year old wanted to go into film....we live in Los Angeles. He started out in that direction, but is now in computers.
The 23 year old wanted to compose musical scores for film, but planned on a double major so he could teach high school music.
He is the closest to what he intended. He's a sound engineer, and still working on music composition.
The 21 year old wanted to go into accounting, but changed his major after a year. He's getting a degree in business and paralegal studies, and wants to go on to law school

As for real estate- it's a tough job right now, but having a goal is a good
