"I do not react to numbers. But they do indicate the success of the film. For me, the feeling that my hard work has been appreciated is priceless. It is because of director A R Murugadoss's vision and script that the film has made a strong impact across the world," Aamir said at a party celebrating the film grossing Rs 200 crore worldwide.
He said he was grateful to his fans for having faith in his films.
Stating that he has no definite success formula, Aamir said he goes by his instinct when chosing the script of a new project.
"I did Taare Zameen Par because I loved the story. I had no idea that it would do the business that it eventually did. It is very difficult to define the potential of any film. When I hear ascript, I react as an audience. I was moved by the tamil version of Ghajini in every aspect. The inner feeling cannot be described," he said when asked how he always picked the winning horse.
Aamir admitted that the stupendous success of Ghajini puts pressure on him to deliver the same results with his forthcoming movies.
"Success is not in my hands. I can only follow my heart and work with all the sincerity and hard work that I always do. I would be happy if my next film 3 Idiots breaks all Ghajini records," he added.
Speaking about the eight-pack abs he specially acquired for Ghajini, Aamir said it had been a "testing time" for him during the one year of training.
"I had to stretch myself to a limit. Losing the physique is also equally strenous. I have to sport a lean look for 3 Idiots and am in the process of losing weight," he added.
Ghajini had a pan-India potential and was also marketed well. Also, audiences had not seen a good action film for a long time, he said.
"When I was offered the film, I was skeptical and felt that Salman or Akshay with well-built bodies could do better. But, it was Surya, the lead actor in the Tamil version, who convinced me that only I could do justice to the role. That is how I got the confidence to go ahead," he added.
Aamir also narrated a story of how late Sunil Dutt had inspired him to take his job as a challenge and with determination.
"I was working with him (Dutt) in Yash Chopra's Parampara. During a particular scene which required Duttsaab to ride a horse, he asked action director Tinnu Verma to bring him a wild horse," Aamir said recalling the incident.
"Duttsaab was able to tame the horse and went galloping through the difficult terrains of Ooty. After ten minutes, the horse was totally under his control. He told Yashji that he was ready for the shot. When I asked him the reason why he had asked for a difficult horse when he could give his shot riding on a tame one, Dutt saab said he did it because he wanted to have "fire" in his shot," Aamir said.
"I realised that he was ready to risk his life for the sake of a good shot. This has inspired me to choose the most unusual films," he added.
On his dream project of bringing the epic Mahabharata on the silver screen, Aamir said it required massive preparations, research and commitment.
"I would love to do it. But not in immediate future. Karna is an ideal role to play, but I do not fit in the role due to my physical appearance. I think I can do Krishna's role," he added.
