In my Olympic history I don't think I have achieved my potential as an athlete. That's what I want when I look back at my career. I want to be able to say I gave it my best shot.

The biggest danger is trying to put too much pressure on yourself, trying to get in too good shape.

I've been to three Olympics and I don't feel I've ever quite achieved my best at any of them.

An Olympic medal won't define my whole life, although it might look like it to onlookers. When I look back, I should have been able to get an Olympic medal.

You see, with me, when I'm nervous, I smile and laugh.

I am not driven by any bitterness by what happened in Athens. I learnt a lot of lessons from it and probably came through it a stronger person in the end. There have been a lot of near misses, and that's taught me to keep persevering and that there is a chance it can come right.

I would be happy with an Olympic bronze. What I don't have is an Olympic medal.
