HE’S KNOWN online now as “America’s cobbler,” but in college, Jim McFarland had no interest in joining his father’s shoe repair business. The small chain of Lakeland, Florida, shops “felt like a family curse,” recalls McFarland, 61. “It’s not an easy way to make a living.” But then his father became ill, and McFarland left college at age 20 to lend a hand while he recovered. “I loved my dad more than anything in the world,” McFarland says. “I had no choice. I had to help him.”
