What is the main conflict in A Hunger Artist by Franz Kafka?

"A Hunger Artist," which takes place in an unspecified time and place, is about a man worldfamous for his public performances of the act of fasting, for as much as forty days at a time. Even at the height of his career, the hunger artist is unsatisfied with his work and frustrated by both his manager and his audiences, who never fully appreciate his true talent or the purity of his "art." The hunger artist struggles internally with his sense of dissatisfaction with himself and his feelings of alienation from the world outside the "cage" in which he fasts.
