The England number one has received numerous plaudits as of late for his performances on the pitch.
Three Lions striker Wayne Rooney hailed Hart as the best in the world after his display against Borussia Dortmund, but the 25-year-old is adamant that he wants to be the goalkeeper that England can rely on.
"It's nice when people say nice things about you, but things are easily said in football and, especially in goal, you can be the worst in the world two days later if you're on TV playing in a game and something bad happens," said Hart.
"You have to remain level-headed. If you don't, it's a big slap when you do make a mistake and people say bad things about you. You can't go too far one way or the other because it leaves you vulnerable.
"Every day I want to be the guy you can rely on. I want to be the best. I want to work hard on saving every shot. I've no silly targets about what I want to do or what I want to win, I just want to keep my love and passion for the game and hopefully good things will come."
Hart has 24 England caps to his name.
