"I never agonised about not practising medicine. I believe you need to find things that you enjoy doing and explore them to the fullest, but don't get stuck with them. I don't believe in this myopic view of our careers, where you have to study something and then you have to work in that career for the next 50 years. It's like buying an expensive hammer and for the rest of your life you've got to be hammering in nails. I really don't believe that. I think medicine, in many ways, prepared me for many other things that I could do. Passion, hard work, honesty and respect for others is something I carry with me wherever I go. I hope that in 10 years' time I will go into something else. I believe in reinventing myself as a human being. There are people who want to stay in a career and explore it to the maximum, but I like change."
