Gatsby's true identity was James Gatz, the son of poor farmers in North Dakota. However, he reinvented himself as Jay Gatsby in hopes of connecting with wealth. He was inspired by Dan Cody's lavish lifestyle and wealth. After observing Cody's exploits, Gatsby learned how the wealthy lived and began throwing extravagant parties in an attempt to fit in with high society. His obsession with reliving the past with Daisy stems from wanting to validate his status and dream of wealth, though that dream is unrealistic and cannot capture the past.
