In "High Fidelity" by Nick Hornby, the process of creating a mixtape is compared to writing a personal letter. This analogy highlights the thoughtful and reflective nature of selecting songs, as it involves constant reconsideration and adjustment, similar to how one might revise a letter to convey their feelings more accurately.
The quote suggests that the act of curating music is deeply personal and requires a deliberate approach. Each choice reflects emotions and memories, just as writing a letter often aims to communicate something meaningful to someone special.
