was so great that he earned a fortune in order to win her love. He tried desperately to get her attention: buying a house across the bay from her’s, throwing lavish parties hoping she’d show up, and according to Jordan "...he says he's read a Chicago paper for years on the chance of catching a glimpse of Daisy's name.” Other characters also clearly realizes that Gatsby's passion for Daisy is driven by overwhelming love Nick says "He had waited five years and bought a mansion where he dispensed starlight to casual moths--so he could 'come over' some afternoon to a stranger's garden." Jordan realizes it too "I think he half expected her to wander into one of his parties, some night,' went on Jordan." (Fitzgerald 63) Gatsby himself doesn’t seem embarrassed about his obsession as he says to Daisy "'Look at this, Here's a lot of clippings about you.' They stood side by side examining it."(Fitzgerald 74).
All these quotations prove that Daisy is perfection in the eyes of Jay Gatsby. In fact, she can do no wrong in the eyes of Gatsby: her admirer. Gatsby has deceived himself into believing that Daisy is beyond perfect. When she acts against his wishes, he has to convince himself over again that she's flawless and whatever she has done wasn't really her fault. Gatsby can not admit that Daisy has imperfections because that would mean his entire dream is a lie since he relies completely on Daisy to complete his dream. As shown, Gatsby went through a far extent to impress someone he needed to complete his dream. This shows exactly who Gatsby is and highlights his character: he has an impulsive drive, is hyper-ambitious, and demonstrates a lack of self control.
His ambition happens to be the American dream which he is feverishly chasing to complete.
