HELP!! ESSAY IDEAS WANTED/NEEDED!!

Hello there! I'm writting on this board as a junior in college, desprate from some help. In my American Literature class I was given the topic of The Great Gatsy- which was my favorite book in HS. My only dilema is I need help choosing a topic to go with the book, and I'm stuck between many options. I don't know which one to pick, and I wanted other people's opinions, if possible.

TOPIC IDEAS:
-The American Dream.
-Symbols.
-Themes in the novel.
-Comparing/Contrast character.
-Analysis on one of the major character (Daisy, Nick, Gatsby, ect.)

**This essay is supposed to be 10 pages, so this is where I get stuck. How am I going to make this essay longer than 10 pages? I usually get to page 5 and start BSING, but I need a good essay/essay topic (counts as my final for the semester- 40% of my grade!) It also has to have 6+ reliable sources, so it has to be somethign I can look up online/in a book. I have 2 sources so far, so it won't be hard to find sources. I also need quotes, but that shouldn't be hard to do. I just need a set topic to fully start this essay, I feel like I'm running around in circles right now with it.

Thank you so much for your help! If you have any other ideas of what I should write about, please let me know. Thank you again! =)
