In many ways, F. Scott Fitzgerald lives out his personal aspirations and fears through his character of Jay Gatsby. Like Gatsby, Fitzgerald often hobnobbed with the social elite, but felt out of place, or like a poser, among them.
But perhaps the most direct parallel to his actual life can be found in the unrequited pursuit of elusive love. Once, on a visit home from college, the young FSF met a sixteen year old beauty named Ginerva King. In the novel, Gatsby meets Daisy when she is a child. Like Daisy Fay in "Gatsby," Giverna was wealthy and far above Fitzgerald's status. She had a sense of privilege and innate superiority and a sensual, seductive manner, as does Daisy.
The parallels between the fictional Daisy and the real-life relationship FSF had with Ginerva King are inconstancy and unattainability. Despite these obstacles, Gatsby's love for Daisy Fay remains constant and so too does Fitzgerald's for Ginerva.
