The defending champions have hammered Pakistan, South Africa and Bangladesh en route to the final, with captain Kohli averaging 253 from four innings.
The key, Kohli says, is to avoid negativity and distractions on social media where he has a fanbase of 65.6 million people across his Facebook, Twitter and Instagram accounts.
"Honestly, it sounds funny, but it's so important to stay away from those things, to connect to things that matter," said Kohli, 28.
"It's tough, but you have to make that sort of effort to stay in a good zone and a good mindset.
"If you're too distracted listening to too many suggestions or players or criticism, you can't focus on what you need to think as a sportsman first to be able to lead the team and then help the others in the team, as well.
"To be able to maintain that balance nicely has been a good thing for me."
India opened the tournament with a 124-run (DLS method) victory over Pakistan and have beaten their final opponents in their past seven meetings in ICC competitions.
Kohli, however, is wary of dismissing Sarfraz Ahmed's team.
"I don't see any relevance of the first game here because you can never tell how a particular team starts a tournament," said Kohli.
"Some teams start very confidently and then they fade off. Some teams might not have the best starts, and they come back amazingly, which Pakistan have done.
"Everyone is aware of the kind of talent they have in their team, and on their day they can beat any side in the world.
"But at the same time, neither are we too intimidated nor are we too arrogant about what we are doing."
