I feel there are two kinds of people in the world: 1) those that believe our world has limitless opportunities and that the best approach of each person is to grow the pie as much as possible, and 2) those that feel the world is a fixed pie, and that they should stomp on, cut up, beat up and do anything possible within the constraints of their limited morality to take as much pie for themselves as possible.
I recently attended the MBA olympics hosted by HEC in Paris. It was a phenomenal event. A huge amount of fun. Thousands of MBA students from all over Europe arrived to compete in a variety of weird and wonderful sports from traditional rugby, soccer, squash etc through to dodgeball, petanque and salsa. One may think that having so many cut throat A-types in one place would be a recipe for disaster, especially in a hyper competitive situation, yet (for the most part) the spirit of the entire event was really inspiring.
