How does nick describe himself at the beginning of the novel the great gatsby?

Nick describes himself as someone who was very tolerant, and withheld judgement from most people. "In consequence, I’m inclined to reserve all judgments, a habit that has opened up many curious natures to me and also made me the victim of not a few veteran bores" (Fitzgerald Chapter 1). He says he graduated from New Haven, and fought in the first World War, which left him feeling restless. He says that he decided to study and attempt to make it in the industry of bonds. He moves to West Egg, where the new money is, or the young men seeking to make their fortunes through hard work, in contrast to East Egg, where the old money is, or family-inherited money. So, in short, Nick is a restless man looking to make his fortune through hard work, and completely reserves judgement of most of the people around him.
