Batting maestro Sachin Tendulkar says he would like to focus on one series at a time rather than thinking too far ahead, including the World Cup that will be held in the sub-continent next year.

"I am not yet thinking about the tour of South Africa and the 2011 Cricket World Cup. My immediate focus is on the upcoming New Zealand series and only when that is over, I will start talking about South Africa," Tendulkar said on the sidelines of a function that marked his association as a brand ambassador with a high-end watch manufacturer Audemars Piguet.

However, Tendulkar admitted that he would be happy if India can maintain the winning momentum in the coming series.

"The momentum is with us right now and we should not let it go. We are not taking anything for granted and want to be on our toes. We would be looking to keep on producing competitive cricket and stick to the basics."

When asked whether he is currently enjoying the form of his life, the iconic batsman who recently completed 14,000 Test runs said that although he is happy but he is still not satisfied.

"There is always room for improvement. I'm happy with my current performance but not satisfied. I want to get better. In fact, in any profession one must strive to get better and better," said Tendulkar, adding, "I always want to remain a student of the game because that is when you grasp more and is always keen to improve."

The 37-year-old, who had one of the most fruitful years of his career in 2010 as he won his first ICC's Player of the Year Award and returned to the top of the world batting rankings for the first time since 2002.

In February, he scored centuries in successive Tests against South Africa before becoming the first man to reach 200 in an ODI against the same opponents.

When asked what all has remained in his wish list which he still want to achieve, Tendulkar said. "There is no wish list. I play because I always love playing cricket. The only thing I ever wanted to do was to play for my country.

"Now, my track is only cricket, where a lot of stations come and I cherish arriving at all of them. But I personally just want to do something for my country and go on playing. In this journey I want to achieve whatever I can till the time remains," said the man, who remains just one short of scoring 50 Test centuries.

"It was a fantastic win the Test series against Australia. In fact, it was great to see some guys produced special cricket. (VVS) Laxman is definitely one such special guy, who snatched the victory for us. He was struggling to even jog as he was injured but he went out there and produced such a brilliant innings.

Tendulkar was the highest run scorer in IPL and also made a Test double-hundred against Sri Lanka before his remarkable performances against Australia which saw him reach the 14,000 landmark in the second Test at Bangalore while scoring 214 and an unbeaten 53 to complete India's 2-0 series victory.
