- Gatsby's mind is occupied singularly by Daisy; everything he does, from the beginning to the end of the book, is done in hopes of catching Daisy's attention and rekindling their relationship. He doesn't understand, or perhaps doesn't want to acknowledge, the possibility that Daisy's feelings have changed and evolved; she did love Gatsby, but she married Tom, and her life is much different now.
- Daisy is long-drifted from his grasp even before the novel begins, but through Gatsby's delusions, he has convinced himself that she is totally attainable.
