When I was in grad school studying architecture and real estate, the Zell/Lurie Real Estate Center used to run a regular lunch series with real estate executives. The way it worked is that executives would come in to the school and 15 or so students -- all of whom were studying real estate -- could sign up to have lunch with them in a boardroom. I can't remember if the school provided us lunch or we had to bring our own, but either way, you had an hour to hear them talk about the industry and ask them whatever you wanted to know.
One time somebody asked a question about what courses they should take outside of their business and real estate classes. And I'll never forget what the executive said. His recommendation was to take courses that were as far away from business, finance, and real estate as possible. He said take fine art history classes, learn about ancient civilizations, or whatever. Just take classes that force you to think a little differently than everybody else.
The reason, I think, this resonated with me so much was because I had a certain amount of academic insecurity at that moment in time. I was coming from an architecture and design background and my classmates were former investment bankers and management consultants, all of whom had a far better grasp of "the numbers" than I did. It meant that real estate recruiters didn't want to talk to me because I was the square peg for their round hole.
