In "Voyager" by Diana Gabaldon, the author emphasizes the futility of attempting to change a partner once a decision has been made about the relationship. Once you choose to be with someone, embracing their true nature is crucial, as attempting to alter them can lead to disappointment. This highlights the importance of acceptance in relationships.

Moreover, the passage underlines that individuals often overlook the need for self-acceptance while focusing on changing others. Trying to impose change on oneself or partners can lead to frustration, as true transformation must come from within. Ultimately, the key to a successful relationship lies in understanding and accepting each other's inherent qualities.
