Indian sides have notoriously played like champs at home and chumps overseas, but Kapil thinks the country's triumph at this year's Champions Trophy in the United Kingdom could prove to be a pivotal moment on the road to the game's showpiece event in early 2015.
"I think recently it's happening, they start believing, it's the self-belief," Kapil said at the tournament launch yesterday.
"We are just hoping we carry on playing the way we are playing," he said.
Kapil said the influx of international players to India for the annual IPL tournament and the subsequent exchange of thoughts and ideas on the game had helped change the mindset of India's cricketers.

"I think possibly the thought processes have changed and that's a good thing for the Indian team," he said.
A key reason behind India's struggles in Australia in particular has been their inability to adapt to different conditions and while Kapil admitted that would be an issue, he felt his country still had the ability to become just the third team in history to achieve back-to-back World Cup titles.
"It's very tough to win in Australia because the conditions is not exactly the way Indian teams like to have but I think they have the team that can win the World Cup.
"I hope they are not peaking too early," Kapil quipped.
The 54-year-old's confidence is based mainly on the successful transition India's ODI side has undergone which has seen them winning series against England and Zimbabwe as well as the Champions Trophy this year.
