H. Wayne Huizenga is one of America's most successful entrepreneurs. He started driving a truck while still in high school and dropped out of college to join a family friend's trash-hauling business. Huizenga bought his own truck and worked his collection route from 2:30 am until noon, then spent the rest of the day hunting for new customers. At age 31, he started Waste Management, with a single garbage truck, which became the world's largest waste collection and disposal company. In 1987, he repeated his business success with the Blockbuster Video Company, which became the country's largest movie rental chain. In 1996, Huizenga formed AutoNation, and expanded it into the nation's largest automotive dealer. He also introduced professional baseball and hockey to South Florida as the initial owner of the Florida Marlins and Florida Panthers, and in the 1990s purchased the Miami Dolphins football team before selling the team in 2009.
