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. ↗
Whatever luck I had, I made. I was never a natural athlete, but I paid my dues in sweat and concentration and took the time necessary to learn karate and become world champion. ↗
On the other hand, chess is a mass sport now and for chess organisers shorter time control is obviously more attractive. But I think that this control does not suit World Championship matches. ↗
What it is saying is that someone who was a world champion and who takes care of himself with a 17-year rest and applies the proper training techniques and perseverance could be successful. ↗
