I think that's one of the first things you'd say if you met me: that I am just nice and smiley. And that's how I might appear when I'm not competing. But I'm totally different when it comes to sport. It's just something that seems to be within me. It's not external or visual. But it's within me.

I think that there's something extremely beautiful about the Olympic ideal and its motto - 'Swifter, higher, stronger' - it's such a beautiful motto, and it celebrates everything which is the antithesis of death and dissolution and entropy.
