I planned to stop in 2002 after the Salt Lake City Olympics. I felt able to remain competitive another four years, and I wanted to stop while I'm still at the top.
I'd been ready too, because before Olympic Games, I wasn't compete in big competition like, World Championship, like European Championship. I just competed in national competition.
I have achieved a lot and I'm grateful for that - I'm just a bit greedy because I want to add the Olympics. It's once every four years - everyone wants it and very few people get it.
I'm hoping that maybe everyone on the Olympic team thinks that I'm worthy to carry the flag. That's my next goal, to carry the flag during the opening ceremonies, if everyone chooses me.
I've put myself forward to be involved. Whether I get picked, we'll have to wait and see. Obviously everybody is excited about it, about the Olympics coming to London and the football being played in different parts of Britain.
As a co-chair of the State's 2010 Olympics Task Force, I am working to make sure our border crossings are ready to handle the risks and benefits the Games will bring.
So as an amateur Olympic competitor I loved criticism, because it made me better. But now as a professional I don't really know how to channel it or where to take it, so I don't take it quite as well.
My coach, Liang Chow, had one rule while I was training for the 2008 Olympics: no skiing. I could do anything I wanted outside the gym, he said, except ski.
I asked my kids, 'Do you know what Papa used to do.' They said, 'You were a boxer, you won the Olympics!' And that's what they know.
The Olympics are only once every four years, so you have to take advantage of all your opportunities, both to be an inspiration to people and help support your sponsors who help you.
I think even if I was to go out there and win the Olympics, everyone's still going to remember the pre-race routine that I do and the video that went viral ,so, y'know, that's alright for me.
When I went to the Olympics, I had every intention of shaving the mustache off, but I realized I was getting so many comments about it - and everybody was talking about it - that I decided to keep it.
Walking the runway with Alexander McQueen, I really had to dig deep. You're with Kate Moss and Naomi Campbell. I was the first person out on the runway, but I thought, 'I have done the Olympics, I can do this.'
If the government announced that it was going to allocate a vast tranche of education funding purely to the pupils at the best public schools, there would be a national outcry - and yet this is precisely what the Olympics represents in terms of sport...
I am very optimistic, and I wish that God almighty grants me success to get a qualifying time. Only then can I go to the Olympics. If this happens I will be the first Palestinian athlete to gain a qualifying time. This will be a big achievement.
You dream about the Olympics for so long and you have that one day, then it's over, and when you don't run well there is this huge letdown. It took me years to deal with that. I feel like I almost had to cleanse myself of that experience.
I really didn't feed off the whole Olympic experience at all, and I regret that from an athletic perspective, and also from a personal experience. I feel like I missed out, so I'm not going to do that this time.
Besides film, I'd like to be the young Regis. That would be great. Going back and forth from L.A. to New York. Doing stuff on food. Doing stuff on kids. Just talking about issues that are relevant. Doing things on the Olympic Games.
The Olympics is a once-in-a-lifetime thing. I was lucky enough to go twice, but most people only get one chance. And in judo you can train your whole life and it'll come down to a split second: You can lose everything or win anything.
I think the Winter Olympics are definitely on a smaller scale than the summer games, but with the inclusion of cool new sports like slope style skiing and snowboarding, it is going to breathe new life into them and attract a whole new crowd.
I've realized the extraordinary power of sports to heal, unite and inspire. I believe the Olympics will serve as the ultimate platform to provide positive changes and I hope to inspire all of Japan through my strong showing there.
