The document is an interview between Ari and Joe DeSena, founder of the Spartan Race. Joe discusses how he created the Spartan Race and Death Race to push participants to their limits physically and mentally. He believes that adversity makes people stronger and helps them reach their potential. Joe applies this philosophy to his own life by engaging in difficult physical challenges every day to "meet his lion". He also trains his two young children intensely in martial arts, wrestling, and endurance sports to build their grit. The interview explores how creating and overcoming challenges can improve one's mental toughness and ability to cope with life's difficulties.
