"Pressure, anxiety and all were always there. In my case, I realised all my preparations were there in a physical sense. After all of that, the anxiety was always there," Tendulkar said in an interaction for Unacademy. 

Tendulkar said that he realised over a period of time how important it is to prepare yourself for matches and series mentally. 

"Even when I was playing for India, there were sleepless nights. Over a period of time, I realised that besides preparing physically for a game, you have to prepare yourself mentally also. In my mind the match started long before I entered the ground. The anxiety levels were very high and I learned to accept to those things," he said. 

Tendulkar, who is the highest run-scorer of all time in Test and ODI cricket and the only cricketer to score 100 international centuries, said that he felt the effects of anxiety for about 10-12 years. 

"Then I started accepting that it was part of my preparation. If I am not able to sleep, fine, no problem. I would do something to distract my mind and keep it in that space where it was comfortable," said Tendulkar. 

Tendulkar played 200 Test matches and 463 ODIs in a 24-year international career. He scored 15,921 runs in Test cricket and 18,426 runs in ODIs.
