The story of the downfall of Rome could inform business owners on the importance of competition. In 146 BC, Rome was the dominant power and went into war with its greatest rival, Carthage. After it ruined the city, the Roman Empire became unstoppable and gathered more victories. Eventually, however, without any more enemies to fight the leaders began to turn against one another until the empire collapsed on itself. Losing competition as a business means losing ambition to continue growing, pushing, and innovating. Making sure to keep up with your rivals as a business is the key to continued expansion.
