Franz Kafka, in his work "Letters to Milena," expresses a poignant understanding of limitations and burdens. He reflects on the impossibility of bearing immense responsibilities alone, symbolized by the weight of the world. This metaphor illustrates the struggles individuals face when overwhelmed by expectations, whether self-imposed or societal.

Kafka further emphasizes the need for balance in life, suggesting that one should not tolerate excessive burdens, like the pressure from others represented by a coach. The quote encapsulates a struggle against isolation and the desire for support, highlighting the human condition's complexity in managing both personal and external challenges.
