In Franz Kafka's "Letters to Milena," the author expresses the complexity of his emotional state. He conveys a sense of ambivalence, indicating that he can be perceived as both struggling and thriving at different times. This duality reflects Kafka's intricate understanding of his own psyche and how he navigates the extremes of his feelings.

The quote, "I'm doing badly, I'm doing well, whichever you prefer," encapsulates this struggle, highlighting the fluidity of human experience. It suggests that one's assessment of their well-being can vary based on perspective, making emotions deeply personal and subjective. Kafka's ability to articulate such contradictions resonates with the universal nature of human emotions.
