Deep Thought Provoking Question....

Last night during our reflection Bill touched on our work ethic. He made the comment that we all put aside our differences and came together to work towards a "common goal." This got me thinking, this statement is really true in our case because I feel like we get "shit" done once we get going, but then why can't the world work like this? Why is it so hard for the world to work towards a common goal? The answer may be simple, but the foundation to the question needs to be thought out.....
