Gatsby

Gatsby believed in the green light, the orgastic future that year by year recedes before us. It eluded us then, but that’s no matter—tomorrow we will run faster, stretch out our arms farther. . . . And then one fine morning— So we beat on, boats against the current, borne back ceaselessly into the past.

These words concluded the novel, and I think they are some of the most powerful words throughout the entire book. This quote ties the story together by giving Gatsby a purpose and almost an explanation. Gatsby has been left as an extremely mysterious character throughout the entire book, however this quote at the end allows readers to have some insight on Gatsby's thoughts and also offers an explanation for the reoccurring symbol of the green light. 
I think that this quote is meant to show represent the difficulties that people face in order to try and fit in and reach their goals. Often these goals are simply just acceptance and trying to fit into a certain standard. I believe that Gatsby really represents the moral that another person's goal doesn't have to be your goal, each individual is different. Gatsby had what many people may consider to be a perfect life, he was extremely wealthy, through extravagant parties, and lived a luxurious lifestyle. However, he lacked love in his life, something so pure that every human needs to feel and is often overlooked. Although Gatsby had so many people come to his parties, very few showed up to his funeral, this shows how easily people can assume someone has a "perfect" life from the outside, not knowing anything about Gatsby himself. "The grass is always greener on the other side" , but people only see the surface, and it is impossible to know what someone's internal struggles are, so do not judge a book by its cover.
