England must "live in the moment" and forget the Barclays Premier League highs and lows to thrive at the World Cup, according to goalkeeper Joe Hart.
The 27-year-old believes neither a mid-season dip in form, nor Manchester City winning the league, will have any bearing on his form in Brazil.
"I was just focused on getting back in the team at Man City to be honest," Hart said, looking back on when he lost his club place to Costel Pantilimon during the league campaign.
"I've learned it's a long season and it definitely doesn't just revolve around myself. There are some great goalkeepers around the world, and we have two besides me at a great club like Manchester City.
"I just knew I had to work hard and try to get to the best level I can be, and that's no different now.
"And I want to give the best options for the manager.
"I'm living in the moment, I'm enjoying things.
"When I was out of the side I worked hard to try to get back in.
"I tried to do my best and that's the same now.
"I'm constantly trying to improve, still trying to cling on to being a young guy.
"I'm trying to improve daily so I'd like to think I'm in a better place than I was four years ago, for the experiences in that time.
"I want to keep improving. The day I stop trying to improve is the day that I finish.
"Hopefully I'll be going on that track for a good while yet."
Hart said Roy Hodgson's side will head to Brazil with the right mindset, and is confident skipper Steven Gerrard will not be affected by his slip against Chelsea that effectively ended Liverpool's title ambitions.
"As soon as we've come into England mode, what happened with the club season doesn't really affect things," he said.
"There's a great feel-good factor heading into a World Cup, whatever happened in the season for any of the lads.
"It's full of England players who want to do well for their country, and it's pretty similar to four years ago in that respect.
"We all want to go out and represent our country as well as we can, represent the people, and it's been like that for years.
"We've had a good two weeks, we've worked hard and the people coming back from injuries have gone well.
"I feel good, the team feels good, we're defending well, we're getting our principles right, listening to the manager and the coaches, and things are going well."
The Shrewsbury-born goalkeeper ended England's 3-0 victory over Peru at Wembley with the captain's armband, but admitted he hopes not to take the honour at any point during the World Cup.
"It's fantastic," he said. "I totally understand the order of Stevie, Lamps (Frank Lampard), Wazza (Wayne Rooney) and myself, but it was nice it ended on my arm at the end.
"I don't want the armband in Brazil, though - I want Stevie wearing it!"
