The Real Gatsby

In the last section I have read of The Great Gatsby by F. Scott Fitzgerald, Nick reveals new information about Gatsby that begins to really shape his character.  First, we learn the extent of his love/obsession for Daisy.  Before Daisy visited him at Nick's house, Nick said "He was pale, and there were dark signs of sleeplessness beneath his eyes (84)."  He was so nervous about seeing Daisy again and about her reaction that he couldn't sleep.  Daisy is obviously one of, if not the most important thing in his life.  He know exactly how long it has been since he last saw her.  "He literally glowed... a new well-being radiated from him and filled the little room (89)."  Then, in the next chapter, Nick tells the real story of Gatsby's past.  His real name is actually James Gatz.  He spent years cruising with Dan Cody, where he became accustomed to excesses which fueled his imagination and aspiration for success.  This name change symbolizes the change in lifestyle from his previous life of hard labor to the excesses of Dan Cody's yacht.  Overall, the two main characteristics of Gatsby that are made clear are his obsession with Daisy and his desire for wealth.
