Bindra, who won gold at the 2008 Beijing Games, said miracle would not happen in short period and sustained efforts in right direction are required to produce better results.
Bindra, India's only individual Olympic champion till date, asserted that results should not be the sole criteria to identify talent and if needed, Western methods must be followed for the purpose.
"Unearthing talents has to be a scientific process. You can't just look at results as the parameters of success at the a young age. I was hopeless as a 12-year-old but I went on to win a gold medal in Olympics. You have to go about in a scientific way to identify talents," Bindra said.
Bindra was speaking during the inaugural Routledge Sports Lecture at Fanattic Sports Museum at Ecospace.

"I see a significant change in attitudes, in recognition and support for athletic journeys, a commitment to better governance, high class infrastructure and knowledge. It is now for us to bring this all together and I genuinely believe that each one of us has a role to play," the chairman of the Target Olympic Podium committee said.
"With Tecnobody I found a machine which tells me the same about my body. I had built the skill to tell if my rifle is imbalanced by a gram. When I stood on the round metal plate on Tecnobody's stability device, a string of sensors measured the minute oscillations in my body. It told me where my centre of gravity was and which way my body was leaning. It helped me fine-tune my stability with real-time feedback."
Bindra also recalled how a misalignment of the upper and lower sides of one's jaw contributed to bio-mechanical errors.
"When I wore the splint the range of motion in my neck improved by 15-20 degrees and this helped me perfect my alignment. I wouldn't have believed this until I experienced it. You could call my story one of 'high performance'. That is a term used quite liberally in elite sport," Bindra said.
"Athens 2004 was a wake-up call. In perhaps the most defining incident of my career I came a disappointing seventh in the Olympic final after shooting what I thought was the perfect game. Only much later did I find out that the lane position I was allotted had a loose tile underfoot.
"It worked for me and came to my rescue even at Rio when my carefully-chosen sight broke minutes before my event. I was able to remain composed and made it to fourth," he said.
The high-profile Indian shooters fired a blank at the Rio 2016 Olympics with Bindra falling by the wayside by 0.1 points in the final but the 2008 Beijing Olympic champion said he has high hopes for Tokyo.
"We can't really make many changes for Tokyo. We have a system in place and a lot of things in place, it's a question of implementing. It takes time to streamline. You can't really change anything but implement."
A member of the Sports Ministry's task-force Bindra said they need to start planning for future.
"We need to start the ball rolling now. In 2020 we have to make best use of what we have, perhaps to try to implement things better, but beyond that we can hope to bring in larger systematic changes which will take time to develop. That work needs to start now.
