He was making a reference to the 2-0 Test series loss to South Africa.
"Every day is learning. If I did not learn from the early days of my career, I would not be here. So, it is always an ongoing process of learning everyday from your mistakes, correcting those mistakes and moving forward. You need to be able to still work on your positives to be a consistent international player over a period of time. I have never stopped learning. I will never stop learning," Kohli told media ahead of the Johannesburg Test.
He added, "It is all about hanging in there and accepting all the faces that are coming. Sometimes team is playing so beautiful that you do not need to do anything. You just relax. This is a part of it. I have gone through bad times personally in my career. Ups and down are a part of a sportsman's career and I understand that. You learn everyday and move forward."
The 29-year old quipped that though cricket is a team game every individual's responsibility to realise his mistakes and rectify them.
Recalling the 2013 Test match against South Africa at the Wanderers where Kohli scored 119 and 96 in the drawn first Test, he said, "I always love playing at the stadium. It is a great vibe. I feel good when I walk into this ground. The last time's Test match was very special, and hopefully, we can have as exciting cricket as we played the last time here."
