"It is their (the critics') job to have opinion. But when I hold a cricket bat in my hand it's a tougher and bigger job. That is what I will concentrate on," Tendulkar said on the eve of the third and final match in the Future Cup against South Africa.
Cricket's longest serving player on the scene had, like the rest of the Indian team, a nightmarish World Cup in the West Indies earlier this year.
He had scores of 7 and 0 in the crucial matches against Bangladesh and Sri Lanka besides an unbeaten half-century against minnows Bermuda, and the team exited in the first round.
That prompted calls for his retirement and he was in fact issued a show-cause notice by the Board for his comments in the media against the then coach Greg Chappell.
Tendulkar and his opening partner Sourav Ganguly, were "rested" for the ODI series in Bangladesh but both of them announced their return with a bang.
The duo shared a 134-run partnership to help India overhaul South Africa's target of 227 and level the three-match series 1-1.
Tendulkar made 4 against Ireland in the lone match against the hosts last week but his 99 and 93 against the Proteas have made the pundits talk about a revival of 'Tendulkar of the old'.
An icing on the cake was reaching the personal milestone of 15,000 ODI runs, which no other batsman has reached so far, in the second match yesterday.
He said his joy was two-fold since his knock gave the team victory and kept their hopes alive in the series.
"It is satisfying, a wonderful moment. After playing for 18 years, I feel it's just one of those things," said the batsman who now has a tally of 15,043 runs from 387 matches at an average of 44.24 with 41 hundreds.
"This match was extremely important for us, to keep alive the series. It's obviously a happy feeling, especially when we ended up on a winning note."
Tendulkar said retirement was the last thing in his mind at the moment.
"As long as the passion is there and as long as I enjoy getting out there on the park, I will keep doing it. At the moment, I'm enjoying it," he said.
Tendulkar was also dismissed in the 90s in the first game after being run out for 99. "If I could get to the 90s every time, I wouldn't mind," he quipped.
Captain Rahul Dravid paid rich tributes to Tendulkar.
"It's a phenomenal achievement, for someone who has played so long to be so consistent. It's incredible," he said.
"Not only do you need skill, you need a lot of mental strength and fortitude to do what he's done, to have that hunger over such a long period of time and go on scoring runs and find new challenges.
"I think he's achieved everything he ever wants to achieve in this game, but it's about motivating himself and trying to do his best for the team and ensure we win games. It's great!," Dravid added.
