Lewis's ambition to be a world-class doctor highlights the possibility of excelling in both career and personal life through a healthy work-life balance and supportive environment.

We push ourselves to the absolute limit. It's about that total commitment. You're getting up around 6:30 in the morning to go out for a couple of hours of training before lectures. It's pretty tough when your legs are throbbing. Then, it's being on my feet all day, from 9:00 to 5:00, shadowing doctors around hospitals. Or being in the bird room at sunup and at night. You know, pushing your body to the edge, where you can't even feel your legs, and you can't afford to let a single revolution slip. I think I must be a bit weird in the head to be able to go that hard.

I'm not doing it for social media fans and followers. Nobody knows who I am, and I quite like that. The thing that motivates me the most is the Commonwealth Games. That focus remains. I've wanted to excel on the world stage and to become the best doctor I can. This season at Cardiff, I was successful enough to qualify for the Great Britain team at the World Championships, which is something I've never managed to do before, even as a full-time athlete. It just goes to show that with the right work-life balance, you can actually excel at both.
