In a book titled 'My Olympic Journey', Sushil recalled that despite suggestions of calling it quits after the Beijing Olympics, he chose to stay on as he felt "it was the start, not the end", and eventually managed to better the colour of his medal four years later at the London Games in 2012.
"I began to build up my game with even more rigour and passion, and the results soon followed," Sushil revealed in a book co-authored by journalists Digvijay Singh Deo and Amit Bose.
"I frankly did not understand the magnitude of what I had just achieved.

"...I wasn't aware till then that a 52-year jinx on Indian wrestling had been ended with my medal. I learnt that KD Jadhav had previously won a medal in Helsinki in 1952. I was happy being an Olympic medallist, but the true worth of the medal would be realized only when I came home.
"In Beijing, a lot of my fellow athletes, officials and coaches congratulated me, but I was used to seeing so many medallists walk around the Village that I did not truly comprehend the weight of my achievement."
"I could not perform to my expectations in the final and was comprehensively beaten. I was disappointed at losing out on the gold, but I knew that on that day, it was the best I could do. As I stood on the Olympic podium again, I was satisfied.
Sushil remembered how the American coaches and wrestlers
chipped in along with his Indian colleagues to bring him back on his feet when he was struggling to cope up with an upset stomach and energy-sapping bouts leading up to the gold-medal round at the London Games.
"The entire Indian team was egging me on, but there was also help from unexpected quarters. The Indian wrestling team would regularly visit America for competitions, and we used to have joint training with the American wrestlers. For some reason, the American coaches were very fond of me.
Sushil believes that the London Games, where the country bagged six medals, broke the cynicism that Indian athletes are satisfied with just participating in the Olympics.
"I was part of that generation that grew up with the dream of being an Olympian. Today, in the wrestling akhara, every aspiring wrestler wants to win an Olympic gold and will settle for nothing less. What delights me is that this mentality isn't limited to wrestling alone; almost every sport today is seeing this change.
