This quote from Peter S. Beagle's "The Last Unicorn" illustrates the essence of true sacrifice and authenticity in pursuing one's desires or ambitions. It emphasizes that genuine effort and commitment require personal investment, often demanding that one gives a part of themselves without the expectation of reward or return. This notion of selflessness is central to many meaningful experiences in life.

The metaphor of offering someone else's liver suggests that relying on the sacrifices of others will not yield genuine results or fulfillment. Instead, it calls for introspection and a willingness to endure personal hardship to achieve real transformation or magic in one's life. In essence, the quote underscores the importance of owning one's journey and the inherent costs that come with it.
