Mark Cuban’s advice for young people starting a business: ‘It really comes down to one simple thing’

Cuban famously got an early start learning to run his own business as a pre-teen selling garbage bags door-to-door in a Pittsburgh suburb. As a college student, he worked as a bartender and taught dance lessons to make extra money. Cuban later showed off his dance skills publicly by appearing on ‘Dancing With the Stars’ in 2007, finishing 8th in the competition. . . .
