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...
Among the world elite there are a handful of athletes who are physically capable of winning it.
To be number one, you must train like you are number two.
Everyone is coming after me now. Fine, let them keep on coming. I'm the fastest man in the world, no doubt.
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.
It's a mental battle trying to come back from injuries and I don't feel like having that mental battle with myself.
I don't think about second or third place.
If you do not train hard you will never fulfill your potential.
When the gun fires you must concentrate for every second on the way to that finish line. You should know exactly how long it will take you to and think about every step of the race you are about to run.
It is only those who believe in their ability who shine when it matters.
You have a lot of emotion at the end of the race. It is not easy to control that when you win.
Every race is not perfect; there are obviously a lot of things I can improve on at the end of the race.
You have to know this: running a 100m race is an intense experience. You have a lot of emotion at the end of the race. It is not easy to control that when you win.
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.
I've had bad jobs. Now I have a good one. I'm thankful.
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.
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.
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.
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.
