New Delhi: It has been four years since Sachin Tendulkar retired from competitive cricket, but the game is so ingrained in his head that he only talks of his life and work in terms of innings. In his "second innings", the master blaster says, he is focussed on doing whatever gives him satisfaction.

Whether it is about associating himself with events and activities getting involved in charities or supporting causes close to his heart — Sachin is looking to "give back".

"The first innings of my life was in the middle of the field, constantly chasing targets set by the opposition. But my second innings is about satisfaction," Sachin said. "As long as there is a purpose behind doing something in life, one will have satisfaction. And that you get only when the heart tells you that, 'Okay, you've done something well,'" he said.

"This is another journey, another chapter that has started in my life. We all try our level best to do various things for others and these give me satisfaction. And I'll continue to do them because this is a longer journey," added the 44-year-old.

Sitting back and reflecting upon how life has played out for him, and how he has played it his way. Now he is going to share the journey with his fans worldwide with "Sachin: A Billion Dreams" — a documentary drama with real-time footage from his personal and professional highs and lows.

A billion hopes, perhaps, will be pinned on him -- once again -- when the movie releases on May 26. Sachin says he can feel the same edge-of-the-seat thrill and anticipation as he felt before he walked into a stadium full of people rooting "Sachin, Sachin" in unison. "It's good for the people to have expectations... I felt that way even on the field," he said.

On his parents and family members, Sachin said: "They were very patient with my 'masti'. My father and mother would never get angry despite my mischief, and that doesn't mean they didn't tell me anything. They told me, but they had a nice way to convey anything and everything in life. And they continue to do so... My mother lives with me.
