How a 28-year-old turned a hobby he picked up as a teenager into a business that earns over 200,000 a month

One of the most important things that ever happened to Dan Faggella was a collapsed roof. The then 25-year-old had been building his own business in his hometown of Wakefield, Rhode Island: a martial arts gym focusing on his specialty, Brazilian Jiu Jitsu. "I was 17 or so when I first learned Brazilian Jiu Jitsu, and I really fell in love with the'chess game' aspect of the martial art," Faggella says. When his teacher's studio closed, he used the money he'd earned from teaching private lessons and working at a local beach to open his own studio, which grew from a rented space in someone else's gym to a 500-square-foot training area to 2,500 square feet of his own. At the same time, he was using his earnings from the studio to pursue what might seem like a very different path: a one-year Masters of Applied Positive Psychology (MAPP) at the University of Pennsylvania, studying under well-known author and positive psychology expert Martin Seligman.
