Tony Coles was about nine years old when he decided to become a doctor. His father, a government accountant and a minister, told him that medicine and law were great professions. The younger Coles, a fan of math and science, opted for medicine. And even when teachers underestimated him, placing Coles in a math class that he thought was too slow and boring, he kept his eye on the prize. “I just held onto that belief that I could be a doctor,” Coles says. “It’s funny how these things can become self-fulfilling prophecies. I don’t believe things happen by accident. I was destined to be involved in some way in healthcare.”
