There are just too many people in the world that believe life isn’t fair and life isn’t fun. I've often had people join companies I've run who's world view is the world and everything in it stinks.
My goal has always been to help people with this attitutde to move to a point where they think about their world in a more positive manner. My ultimate goal has always been to have those around me me think about we and how we can make the world (or at least our company) a better place.
