there is a quote in the book before the first chapter...

Can you let me know what the quote is? I don't have my copy here.

the quote is:

Then wear the gold hat, if that will move her;

If you can bounce high, bounce for her too,

Till she cry 'Lover, gold-hatted, high-bouncing lover,

I must have you!'

This relates to Gatsby trying to lure Daisy to him using his massive wealth and the illusion of happiness.
