You need three things to win: discipline, hard work and, before everything maybe, commitment. No one will make it without those three. Sport teaches you that.
Some people start a sport just to reduce weight, or some say, 'My doctor ordered me to run and do exercise', and for others, they run for completely different benefits. But it is not like that with sport. We need to eat, we need to rest, but also we need to run.
My father thought sport was something fun - he didn't know it was a way to make money. Then I won a Mercedes at the world championships and I gave it to him. From the moment it arrived my father said: 'Good, you can support not just yourself but me too'.
That is not enough. Sport has been great for me, a great learning place that if you want to achieve you can, even if you are from the poorest part of Africa.
