Fitness icon Tony Little, known for his energetic personality and salesmanship, had to fight through hard times to find his entrepreneurial spark.
After a near-fatal car accident in 1983, Little suffered through a long physical recovery, depression and a resulting addiction to painkillers.
"I was in an and out of hospitals for two years and lost my body-building career," Little told CNBC.
But one day, while watching Jane Fonda's exercise show on TV, Little decided he was done being miserable.
"I said, 'I'm going to do that,'" Little recalled. "When you change your mindset, you change your life."
