'A' tours can be considered as a stepping stone to getting into the national team, so they are really important.
When you go out to play in different conditions against different bowlers, it is always challenging.
I remember when I was a kid, I would visualise wearing the India colours and walking on the field in front of an amazing atmosphere, and I feel it has helped me a lot throughout my career.
At the start, when I started playing first-class cricket, I was a flamboyant player and I never used to take responsibility.
I just used to back my instincts and go with the flow. Lately, I've realised that once you play at the highest level you've got to take that maturity to another stage.
