How was dan cody involved in shaping gatsby into the man he is now?

Gatsby's dreams of self-improvement were only intensified by his relationship with Dan Cody, a man whom he met while working as a fisherman on Lake Superior. Cody was then fifty, a self-made millionaire who had made his fortune during the Yukon gold rush. Cody took Gatsby in and made the young man his personal assistant. On their subsequent voyages to the West Indies and the Barbary Coast, Gatsby became even more passionately covetous of wealth and privilege. When Cody died, Gatsby inherited $25,000; he was unable to claim it, however, due to the malicious intervention of Cody's mistress, Ella Kaye. Afterward, Gatsby vowed to become a success in his own right.
