The 26-year-old batter was speaking ahead of India's five-match T20I series against the West Indies, which begins on Tuesday, October 6, with Shreyas Iyer captaining the side.
Sharma believes winning a major tournament is only one achievement, with sustaining high standards across multiple series requiring a different approach. He emphasised that India will need consistency, a strong collective mindset and a shared determination to keep performing.
The young batter also highlighted the importance of a positive team environment, stressing that individual contributions must be backed by a united dressing room. According to Sharma, every player needs to remain focused on the same objective if India are to maintain their level.
"I feel, in cricket especially, when I came, I was 24, now I am 26, as a young cricketer you tell yourself that there's still a lot to achieve, it's just a start," he told JioStar.
"Doing it once, I feel, is still easy, but making that thing a habit and doing it again and again, keeping the process the same, it's not easy as a player.
"But if the atmosphere in the team is such that everyone wants to perform for each other, wants to make India win, wants to dominate, then I feel it becomes a habit and it definitely helps."
The series marks the start of a new phase in India's T20 international schedule and will provide an early indication of whether the team can carry its World Cup standards into the next stage of its campaign.
