The Green light that Gatsby sees beyond the bay is a sign of hope. The light is symbolic of Gatsby's longing for Daisy, but the green light also means much more. Gatsby spends his whole life longing for something better such as money, success, acceptance, and of course, Daisy. And no matter how much he has, he never feels complete. While owning a large house full of interesting people and all of their attention, he still longs for Daisy. He creates a place for her in his dreams, and he will not be content to have that gaping hole. So the green light stands for all of Gatsby's longings and wants. And when Nick talks about the green light at the end of the book he says "It eluded us then, but that's no matter- tomorrow we will run faster, stretch our arms out farther.". He connects the green light to all people. Everyone has something that they long and search for that is just off in the distance. That is the green light.
Fitzgerald uses the word careless a lot in describing most of the people and events in this book. There seems to be no fear of consequence, of judgment. So who is doing the judgment? That is, in part, what the eyes of T.J. Eckleburg are there for. These eyes are from a billboard that looks over a wasteland including Wilson's garage. The eyes are always mentioned whenever Nick is there. They look over the situation, objectively, but offer a kind of judgment on the characters and their actions. They are placed near the Wilson's because that is where some of the most selfish acts take place such as Tom's affair with Myrtle Wilson. The relationship between the two can be described as a superficial relationship. Tom's secret affair with Myrtle quickly comes to an end once he finds out that Jay Gatsby still longs for Daisy. From there on, Tom begins to do everything he can to corrupt Gatsby's dream. Also, the ongoing confliction between Tom and Gatsby for Daisy could have been the cause of Myrtle's death.
