Before joining the Clarets in 2013, Heaton was at Manchester United, but spent most of his time out on loan.
"Obviously I have played across all four divisions," said Heaton. "The ambition never left me, that hunger to play for England.
"It might have felt, for other people, a long way off at certain times, playing down in League Two, but I never lost that belief.
"It is a different sort of journey to a lot of lads, but I am proud of that journey. Started at United, left, went away, sort of worked back up to the Premier League. I wouldn't change it.
"It is what it is. I like to think it stands me in good stead in terms of the experiences and perhaps the mental side of it."
