I can still improve a lot, but there is definitely a limit to what the human body can do.

I remember when I was 14, I went to race in Hungary, and I went to a concert, and they were playing Bob Marley songs, and I thought, "Wow, this guy is so special." It's Marley every time.

I don't listen to music before a race - my coach doesn't like it, he thinks I might lose my focus and concentration.

Easy is not a option..No days off..Never Quit..Be Fearless..Talent you have Naturally..Skill is only developed by hours and hours of Work

I am doing what I do [athletics] because the fans love it and it's a part of me, it's my personality. I think people come to see you run fast, but they also come to see a show, a performance. They want to see a personality, and that's what I give them.

For me, time is everything, because from the time you wake up you have to have your heart and soul in this. You have to work through the day, you have to go to the gym, you have to eat, and yet you have to work as fast as possible to get home and get rest before the next day begins again.

As long as I'm in great shape, nobody beats me, for sure.
