Last year I was the favorite going into the world champs in Beijing, but I felt like I had to do something phenomenal in order to win. Instead of just having fun and competing, it became "I want to win so bad." But the person who wants it the most doesn't win. It's the person who executes. I still look back on that 200-meter race and say what the hell happened? I wasn't hurt, I wasn't sick, the conditions were perfect, and I ran like total crap.
