What Did Dan Cody Do For Gatsby What Did Gatsby Learn From Him?

Chapter 6 of The Great Gatsby by F. Scott Fitzgerald tells about the turning point of Gatsby's life when he met Dan Cody.
At the beginning of chapter 6, a reporter goes to Gatsby’s mansion to interview him. It starts with Gatsby’s actual story, not from Gatsby’s perspective or other people’s rumors. Nick narrates Gatsby’s personal history and we learn that Gatsby isn’t his real name, James Gatz is his real name. We learn that Gatsby drops out of St. Olaf after two weeks was working in at Lake Superior collecting clams and fishing for salmon. 'He saw a yacht owned by Dan Cody, a wealthy copper mogul,' and rowed out to the yacht to warn Dan Cody about the disastrous storm. 'The grateful Cody took young Gatz, who gave his name as Jay Gatsby, onboard his yacht as his personal assistant.' That's when Gatsby falls in love with luxury and wealth.
Dan taught Gatsby everything he knew, he game him a new name and a new lifestyle. It was mentioned that Dan Cody attempted to leave him his inheritance but his mistress got in the way, yet, the most important thing Gatsby received from Dan Cody was how to act rich. Dan Cody is also a major reason as to why Gatsby does not drink much, seeing as how Dan Cody was frequently drunk.
