I have been asked by people of various sections as to the wisdom and possibility of Judo being introduced with other games and sports at the Olympic Games. My view on the matter, at present, is rather passive. If it be the desire of other member countries, I have no objection. But I do not feel inclined to take any initiative. For one thing, Judo in reality is not a mere sport or game. I regard it as a principle of life, art and science. In fact, it is a means for personal cultural attainment. Only one of the forms of Judo training, so-called randori or free practice can be classed as a form of sport. Certainly, to some extent, the same may be said of boxing and fencing, but today they are practiced and conducted as sports. Then the Olympic Games are so strongly flavored with nationalism that it is possible to be influenced by it and to develop "Contest Judo", a retrograde form as ju-jitsu was before the Kodokan was founded.

I saw the struggle of the champions of this discipline and read various articles about it. At this time, I realized that this sport is one of the strongest martial arts in the world and the name of this sport is "Cage Fighting". "Working in this field and learning their tricks and techniques tempted me badly.

It was pure chance that led me to judo. Judo has helped me to understand that pictorial space is above al the product of spiritual exercises. Judo is in fact the discovery by the human body of a spiritual space.

I learnt that it was possible to compete with anyone from any part of the world, one on one, and win.

It came mainly from my desire to learn more about the Japanese culture. I've also always been fascinated by social groups who live and work outside the mainstream. So the world of sumo wrestling within the Japanese culture had been an ongoing interest, something I've always wanted to write about. It covered such enticing material and I've always had so many questions I wanted answered…

I went and saw a lot of them at their daily practice of fencing with bamboo sticks and practicing jiu-jitsu to make themselves strong and active and good-tempered. I say good-tempered because it is very much like boxing; you have to take a good many hard knocks and take them smiling. If a fellow lost his temper at it, everybody would laugh at him and think him a fool. In jiu-jitsu they learn how to exercise and how to develop their muscles, how to catch hold of an enemy in many different ways so as to overpower him, how to throw him and, what is very important, how to fall easily if they get thrown themselves. I expect the Scouts of Japan, if they visit England later on, will be able to show us a thing or two in this line.

I learnt kushti (wrestling) and music simultaneously,

Zenit was always in my heart. That's where I won my first European title. When I left Saint Petersburg in 2009, the fans followed me to the airport, and I promised, I will return to Russia.

I started playing judo and kung fu at an early age.

Judo is the way to the most effective use of both physical and spiritual strength. By training you in attacks and defenses it refines your body and your soul and helps you make the spiritual essence of Judo a part of your very being. In this way you are able to perfect yourself and contribute something of value to the world. This is the final goal of Judo discipline.

I went round to all these minority sports and I couldn't really appreciate them. Fencing, for example, is just "click, click, click" and it is over. Then they retire. Then they go again "On guard — click, click, click" and it is over again. You just think, "what is this sport?" I thought this is really boring and then I went to Judo and it was just the same thing. These two guys just endlessly circling each other, acting as if what they are trying to do is take the others shirt off without him realising this is what they are trying to do. I just thought "what is this? I don't understand this at all". Then I went to table tennis, which obviously I could identify with because I had played it myself — not quite at Olympic standard — but I could understand it. It suddenly became clear to me that these people really are so far beyond anything I could ever dream of becoming. I felt really terrible because I hadn't appreciated the fencers. The reason I couldn't follow them was because they were so damn good. Their hands were so quick that I couldn't see what was going on.

I started out like most people just finding my local martial arts gym … and it's quite easy to start thinking that whatever you're in is the best thing that you can do, so … I assumed that Taekwondo is the best. … I started thinking, “Well, maybe there's something else that the other arts have offer,” so I started cross-training. Anyway, that got me into competing in mixed martial arts. So, I thought my diet was pretty good … and it was until I got injured … that I actually had some time to sit back and really analyze what I was eating, and I realized I hadn't applied the same scrutiny to my diet as I had to the martial arts training. So I saw a parallel there, that in martial arts there's a lot of nonsense out there, people teaching stuff that really doesn't work, and I'd realized that and started finding the truth in martial arts, and basically I realized I hadn't found the truth in nutrition, so last year I spent over 1,000 hours looking at peer reviewed medical science and realized that a plant-based diet is superior and optimal for health and athletic performance.

Judo teaches us to look for the best possible course of action, whatever the individual circumstances, and helps us to understand that worry is a waste of energy. Paradoxically, the man who has failed and one who is at the peak of success are in exactly the same position. Each must decide what he will do next, choose the course that will lead him to the future. The teachings of judo give each the same potential for success, in the former instance guiding a man out of lethargy and disappointment to a state of vigorous activity.

It wasn't actually in the Olympic Games, but I spent 12 years on the national squad. And it was a great experience, you know, to travel the world and compete at a certain level. It teaches you discipline, focus, and certainly keeps you out of trouble.
