Why did R. Schumann abandon his dream to be a virtuoso pianist?

Robert Schumann abandoned his dream of becoming a virtuoso pianist primarily due to a hand injury that significantly affected his ability to play. This injury occurred when he attempted to develop a mechanical device to strengthen his fingers for piano performance, which inadvertently damaged his hand. The physical limitation imposed by this injury was a turning point in Schumann's life, leading him to shift his focus from performance to composition and music criticism. His subsequent compositions, particularly for piano, demonstrate his deep understanding of the instrument despite his inability to perform at the high level he desired. This transition ultimately allowed him to become one of the leading composers of the Romantic era, even if it meant sacrificing his aspirations as a pianist.
