Ed recently sent me an interesting article written by Malcolm Gladwell about David versus Goliath. Like his books, the article dives deep into a difficult subject, and masterfully explains something that seems unexplainable. I won’t go too far in the article, as I will post the link so you can read it yourself, but his theories, and his way of of blending historial and more modern examples together, form a great argument to help explain how Davids have a chance against the mightiest Goliaths.
