In Joseph Conrad's "The Secret Agent," the text explores the connection between one's profession and personal identity. It suggests that when individuals are involved in work they dislike, it negatively impacts their self-perception. The dissatisfaction in their roles not only taints their professional lives but also seeps into how they view themselves, leading to a loss of illusions about their capabilities and self-worth.

Moreover, the passage emphasizes that true fulfillment comes when a person's work aligns with their genuine interests and temperament. This alignment offers a sense of comfort and authenticity, allowing for the possibility of self-deception that can be comforting. Ultimately, the text reveals the profound influence of our chosen endeavors on our overall sense of self and happiness.
