'I use my Olympic medal as a confidence-builder that
I'm the best, and now I use the World Championship title as a way to feed off of that. I'm the world champ and I know there are a lot of people gunning for me, but if I prepare for all my fights the way I prepared for the worlds and I go in there and fight to my ability, I will come away with gold. Judo is a weird sport - anything can happen and one mistake and you're out of the tournament. But when all goes well and I fight smart - I don't make any mistakes - I know that I'm going to come away with a gold medal.'
