When David Eustace of Scotland decided to quit his job as a prison officer to become a photographer, his peers told him he was crazy. “What if you fail? What if it doesn’t work out?” David asked himself different “What If” questions: “What if it’s wonderful? What if I succeed?” David’s risk-taking paid off big-time. He became a photographer in New York for magazines like Vogue and GQ. But that was just the beginning. He got other job opportunities that led him to fulfill his ultimate dream: visiting the desert states of America, taking the trip with his daughter and making what he calls the “most meaningful portfolio” of his life. In the following talk, David beautifully urges people to follow their passions and overcome self-doubt.
