It is only those who believe in their ability who shine when it matters.

You have got to believe in yourself every time you go out there and race. If you have no faith in your ability all that training has been a waste of time.

You'd like more people to recognise what you do is special. But I take the attitude that the best thing I can do for my sport is to be the best at it. The best way people will come to recognise that track and field is a great sport is to see athletes excelling at it. Which is what I intend to do.

Among the world elite there are a handful of athletes who are physically capable of winning it.

Athens is a great place for me. It is my second home. It's where I won my first world championship medal, it's where I set my world record.

Every race is not perfect; there are obviously a lot of things I can improve on at the end of the race.

Everyone is coming after me now. Fine, let them keep on coming. I'm the fastest man in the world, no doubt.

I don't think about second or third place.

I have a God-given talent and I work very hard for what I do. Anybody can run fast. It's how you run fast. I pay attention to technical things now.

I love running in Europe, man, running at places like Zurich and Crystal Palace where the crowd is so knowledgeable and appreciative.

I've had bad jobs. Now I have a good one. I'm thankful.

If you do not train hard you will never fulfill your potential.

It's a mental battle trying to come back from injuries and I don't feel like having that mental battle with myself.

The world record will come to me when I run the world record race. I'm just trying to perfect my race. I'm looking for perfection.

To be number one, you must train like you are number two.

Weather is uncontrollable. Only the Lord above can control the weather. Whatever we get, we have to work with.

You have a lot of emotion at the end of the race. It is not easy to control that when you win.

If you look at the sponsors who were in the sport 15 years ago compared to now there are a lot fewer. Why? Because those runners who took drugs tainted the sport. They tainted all of us in it.

In America, we have three major sports - baseball, football and basketball. They get the most coverage. Then there's things like golf which mop up most of what is left. But track and field? We are way at the bottom of the totem pole.

My stance has always been that there's no place in our sport for drug users. I've always said it's a ban for life if you come up positive. I stand by that.
