Hart has spent this term largely on the bench at Turf Moor.
“The fact that I sat on a bench for a year and a half in Premier League matches will not change or break me," he told BBC Sport.
“I remember who I am.
"I remember playing in the local league of my hometown on Sundays and dreamed of getting into the Shrewsbury team. I understood early that I needed to look at everything in perspective.
"Great things can be said about you as a football player, but you must remain self-critical and analyse your actions. Maybe from the side for people it seems that I have come to panic, but I see the situation as a chance to look for new opportunities.
"For a goalkeeper, I'm young enough. Of course, I have no illusions, I do not expect that they will call me from Real Madrid now and say they'll kick out (Thibaut) Courtois and are going to take me in his place.
"However, I still have opportunities. Someone needs to believe in me, and then I will fully repay the trust for this."
