The 40-year-old "Paa" star, who welcomed his daughter with wife Aishwarya in 2011, says nothing could have prepared him to become a father.
"There will always be so many people, who will give you advice about parenthood but at the end of the day you will find your own footing with it. Your life really changes after this.
You become responsible for this bundle of joy," Abhishek told PTI.
The actor believes that he and his actress wife's life is all about their daughter.
"Everything in your life after becoming parents, changes.
At least for me and Aishwarya, it is all about Aaradhya and how it will affect her from small things to the largest decisions.
It has to be something that has to be seen from her point of view. So, it changes evrything for good," he said.
Abhishek, who is the face of Omega, was in the city recently to launch Globemaster watch from the brand.
