They may have taken a strategy course somewhere or worked in a strategy planning group somewhere, so they start off with a closed mind. When the professor trys to teach a concept, or when their classmates speak out, they don't take them seriously. You are now learning from some of the best brains in the world. Listen to your professors because you are going to learn a lot from them, and that is going to save you time. And saving time means survival around here.
People think competition is the name of the game.
Of course, competition is very important and we teach that here at business schools. We meet, and I end up giving them all the 80 percent of the material they need and I only get 20 percent from them. Then they may decide that they don't want to participate because they think the other people are too far behind. If you don't work with a team you are stuck with the 80 percent that you already know. If you do participate, you are going to learn that 20 percent and ultimately end up with 100 percent.
