The opener did not get to play in the Test series and is keen to make amends in the five-match ODI series starting on Sunday.
"Firstly, it is a huge honour to be appointed as the vice-captain. Ten years ago, I was only thinking of playing for India. Being the vice-captain now feels really, really good," Sharma said today.
"It's a kind of honour that whenever the opportunity comes, the first one-dayer when we come on August 20, there will be some sort of role that I will need to play and I am looking forward to it. I am not thinking too much about it. I just want to enjoy the moment as of now."
When asked to about compare his IPL and the newly assigned role with the Indian team, Sharma replied, "It's a different ballgame completely. IPL and when you come and play international cricket, it is completely different. But again, the excitement and the energy level is the same.

"So yes, nothing changes too much. I am the vice-captain here, there I was the captain, and so I was more in front. Here I have to play a little behind-the-scene role. But yes, I will be very excited to step on to the field as the vice- captain."
"Firstly, it's gone very fast, those ten years. Yes, there has been ups and downs but that's how it is for any sportsman, and that's how it should be. You get to learn a lot more from ups and downs.
"I always wait for this opportunity, whenever I get this opportunity, to play for India, whichever format it is. Before those ten years, I never thought I would play for India.
He has spent more than a decade in international cricket but Sharma still treats everyday as a new day.
"Today I got to learn playing those sweeps and reverse sweeps when someone like Lasith Malinga comes and bowls to you. So everyday you enter the field you go on to learn something new.
"You got to understand the situation, the conditions and that's what I have learnt over these years with so many coaches around. I will still continue to learn and that is the greatest part of this sport, that you learn everyday and there is something to look forward to every day," he said.
It was not a good feeling, said Sharma.
"Nobody likes to sit out. But again, it all depends on the team dynamics, what the captain and the coach wants to play. And you got to accept the fact and move forward.
"I kept working on my skills, my ability, wherever I need to work on and see where I can improve as a cricketer. You cannot sit here and waste time.
"All I was trying to do these past 3-4 weeks was just to improve my skills, see where things are going wrong and try and strengthen the strengths I have."
The batsman was one among three players, along with KL Rahul and Axar Patel, who took part in optional nets here today.
"I have had some good times against Sri Lanka and at the same time I have had some terrible times against Sri Lanka in 2012, which I clearly remember and it is something that happens in sport.
"I have played these guys so many times now, we have come to Sri Lanka many times and we understand the conditions well. You know the kind of cricket you want to play, and the opposition, and the kind of bowling dynamics they have. We played these guys a lot many times and that will help.
Though India beat Sri Lanka comprehensively the Test series, Sharma warned that it will not be easy against them in the 50-over format.
"I have no idea about their squad for this ODI series but what they had in the Champions Trophy was a very good side. They beat us quite comfortably. Chasing 320 was never going to be easy especially in those conditions but they came out and batted fearlessly and took the game away from us.
