I never let anything stop me from doing what I want to do.

My goals were last year to win the world champs and this year to win the Olympic Games and I've done that and I couldn't be happier.

But I'm after medals more than anything. Championships don't get taken away from you but records do, so I think I'd rather have medals at every championships rather than times. A world record would be a bonus, but I'm still only 25 in 17 days.

Being at school, being who I am, being an athlete, it was hard to find people like me. There's not many athletes that can be at my level. That was kind of hard finding people who love something so much they want to keep on doing it.

If you hold back in hurdles, you are going to fall over.

My job is my sport so I have to make sure that I stay focussed on it. I train almost every day so it takes up a lot of my life and you don't want to bring any new distractions into your life.

Some people are used to having things done for them by her parents, I am not. I can do it myself.
