The actor, who plays the key role of Jagdish aka Jagya in the Colors' show, says he was nervous and unsure of his acting skills when he stepped into the show in 2010.
"Now I can say I can act! When I started my journey, I was nervous. I was worried about how I will cope up. Now I am quite confident of myself and of the show as well," Shashank told IANS.
He says "Balika Vadhu" has been a learning experience.
"It feels good to know how much people like the show after three years also. I am working with senior actors and working with them is a wonderful experience. I see my (acting) graph rising now," he said.
However, he admits that his real challenge will only come after "Balika Vadhu".
"My next journey will decide my career. This is my debut show and people accepted what I played. In my next show, it will be a challenge for me as an actor," he said.
Shashank entered the social issue-based show when it took a leap in July 2010.
Most TV shows are being pulled off air barely after a few months of their launch, but in the case of "Balika Vadhu", its story has made it a success, says the actor.
"As far as daily soaps are concerned, writing is the main thing. There are so many brilliant actors, but if the work on paper is not good, you can't do anything," he said.
