I've got quite a good poker face. I'm known for being able to keep my emotions very much in check: no one knows how I'm feeling. I can be winning or losing but keep it very much the same.

In our sport, there's only two people, so if you're not winning, then you're losing.

I'm lucky in that I can't see myself doing an office job every day. I'm lucky that I can play my sport and go around the world without too much to worry about outside that. I think it's good to be happy with what you're doing.

I was quite short and chubby until I was 14, when I shot up.

I think if people were to look at badminton and tennis, they'd see they're actually very similar; the profile would increase, and we might be in a better position as a sport.

Obviously, you need talent to do well in your sport, but I think hard work goes a long way. You need to be lucky within the sport too, though. In badminton, you can benefit from good draws and people getting injured.
