People who have experienced the results that only come from hard work understand that those results are reserved only for those willing to work hard. People who watch others achieve rarely see the hard work and grind that goes into achieving and therefore decide that it is the result of random luck or privilege. Teams with a great work ethic understand winning at anything in life is never a privilege because they have worked hard and lost as well. This is why we never see a team have a great work ethic with an ego problem. We never see a team with an ego problem work hard enough either.
