I can have my goals, and I can have my dreams. My goal is to make the finals and improve my position. I want to run all decent races. I don't want to look back and say I ran a terrible race.

Rio in four years; I've got more inspiration in the last two, three weeks. I'm sure I'm going to get more in the Paralympics in the next coming weeks, so by the end of this season, I'm going to take a month off, and then the next four years is going to be good.

Oscar Pistorius is on the cusp of a paradigm shift in which disability becomes ability, disadvantage becomes advantage. Yet we mustn't lose sight of what makes an athlete great. It's too easy to credit Pistorius' success to technology. Through birth or circumstance, some are given certain gifts, but it's what one does with those gifts, the hours devoted to training, the desire to be the best, that is at the true heart of a champion.
