In Miguel de Cervantes Saavedra's "Don Quixote," the protagonist embodies the idea of pursuing one's own path and ideals. He believes deeply in his vision of chivalry and adventure, seeing himself as a noble figure fighting against wrongs. This conviction ultimately leads him to act autonomously, asserting his belief that he is the best at what he does, regardless of the reality surrounding him.

Don Quixote’s pursuits symbolize a quest to combat the greatest challenges he perceives, much like a doctor treating diseases. His determination and unwavering spirit reflect a larger commentary on individuality and the human desire to enact change in the world, even if it seems misguided or out of touch with reality.
