The quote from Diana Gabaldon's "Outlander," suggests the idea that when one comes to understand that all possibilities are open to them, the pressure to pursue specific goals or desires diminishes. This realization can lead to a sense of freedom, where the weight of necessity is lifted. Instead of feeling constrained by what must be achieved, a broader perspective opens up, encouraging exploration of life's potential without the burden of obligations.

This notion also reflects a common theme in literature, where characters find themselves at a crossroads, realizing that their choices are not limited. In "Outlander," this sentiment resonates with the journey of the characters as they navigate the complexities of time travel, relationships, and self-discovery, ultimately embracing the vast possibilities of their lives. The awareness that "nothing is necessary" can be both liberating and daunting, prompting individuals to reflect on their true desires and the essence of fulfillment.
