For one of my classes, we had a semester long project to design the most profitable casino given 30,000 sq ft of casino floor. It ended up turning in to an 80 page, 25,000 word business proposal. Easily the most work I have ever done for a single project in all my years of schooling, but damn did it turn out well. Isn't it a great feeling to hold your work at the end of it all, and realize that you made that?
