Hart has been the first choice for the Three Lions between the posts since the 2010 World Cup finals in South Africa.
"It's nice now for people to say that I could be England's keeper for the next 10 years but plenty of people won't agree," the 25-year-old is quoted as saying in the Daily Star.
"Goalkeepers can have a long career and right now I'm enjoying my role in the England squad. I want to make that last.
"I will try to give it everything for my country. I would love to get to 23, then 25 and 30 caps. They are things I love to do every time I line up. It's a great feeling."
However, Hart refuses to take it for granted that he will continue to retain his place for England without remaining at the top of his game.
"I know how quickly things can change in football and I am only where I am because someone else lost their place," he said.
"Nothing is a given, especially when you see the standards in the two sides I play for, City and England.
"I play for one of the best club sides in England who want to be one of the best sides in Europe. And England as a nation are one of the best countries about."
Hart will be in action for England when they take on Moldova and Ukraine in the 2014 World Cup qualifiers this month.
