I think one of the true gifts that one can have is to find out what it is that they truly love to do. For some people it’s playing the piano. For others it might be swimming, or some sort of athletic event. To me it was science, and I happened to get lucky enough to find my love for science, which I still love. What that allows me to do essentially is — as a scientist and as a neurosurgeon — I don’t work when I go to work. I mean it’s what I love to do. If I didn’t get paid for what I wanted to do, I would want to pay to do it. So one is very blessed to find what it is that they love to do. The other thing that it does, it allows you to really devote the focus, the hours, the intensity into whatever it is, to become very good at it. Whatever you do, you’re going to have to spend a lot of time perfecting your craft, perfecting your art. So if I’m up late working on a research project, or working to save a patient’s life, it’s not work for me. It’s what I enjoy doing, and it’s not difficult to do if you’re having fun.
